Your xorg.conf is a little strange (there are no resolutions defined in your "Screen" section), but I'm no expert on xorg.conf files, so I can't see anything that would cause VT corruption. As for switching to the generic kernel, here are some instructions (copied from another thread).
You probably should be using the generic-smp kernel, as the huge-smp kernel is really meant just for the installation. You can use the huge-smp kernel with no ill effects, but it requires a lot of blacklisting of modules to avoid errors and tricky behaviour (which may be difficult to track down). You should think about switching to the generic-smp kernel (which requires an initrd!!) at some point (soon would be better). I would definitely suggest leaving an entry in /etc/lilo.conf for the huge-smp kernel though -- because of the requirement for an initrd, if you screw anything up (or if something gets screwed up with future kernels that you may decide to compile or upgrade etc.) the huge-smp will ALWAYS boot properly (it's very handy). To switch to the generic kernel, add an entry in /etc/lilo.conf that will boot that. The lilo entries for the generic-smp and huge-smp kernels can be done as follows:
Code:
image = /boot/vmlinuz-generic-smp-2.6.21.5-smp
initrd = /boot/initrd.gz
root = /dev/hda1
label = Generic Kernel
read-only
image = /boot/vmlinuz-huge-smp-2.6.21.5-smp
root = /dev/hda1
label = Huge Kernel
read-only
NOTE: change /dev/hda1 in each of the above entries to wherever your root partition of your hard drive is (use the existing huge-smp entry as an example). Note that in a default setup, /boot/vmlinuz is a symbolic link to /boot/vmlinuz-huge-smp-2.6.21.5-smp, so the lilo entry points to that instead of what I wrote above. You could always just symlink /boot/vmlinuz to point to the generic-smp kernel instead and avoid adding an entry, but then you don't have the backup huge kernel, which is very handy in an emergency.
After you edit /etc/lilo.conf (and BEFORE you run lilo), you must create an initrd (initial ramdisk). Read '/boot/README.initrd' (which is a symlink to /usr/doc/mkinitrd-1.1.2/README.initrd) and it'll tell you how to make an initrd (since I use reiserfs, I simply typed `mkinitrd -c -k 2.6.21.5-smp -m reiserfs` as root). That should create a /boot/initrd-tree directory and a /boot/initrd.gz file. You should also symlink System.map to point to System.map-generic-smp-2.6.21.5-smp instead of System.map-huge-smp-2.6.21.5-smp, but it's not essential (I've had mismatched System.map symlinks before because I forgot to change the symlink and had no problems whatsoever -- however, for correctness, it should be done).
After all that's done, run `/sbin/lilo` as root to update your MBR. Then you can happily reboot into the generic kernel. If anything goes wrong, you can simply boot using the huge kernel (that you hopefully created a lilo entry for) and your system will be back up and running with no ill effects, allowing you to remedy the error you may have made using the generic kernel.
