Lost console after kernel upgrade

[Bill Moseley <moseley@hank.org>]

I upgraded from 2.6.5 to 2.6.9 today -- I used the debian
kernel-source-2.6.9 package and copied the 2.5.6 .config file into the
2.6.9 directory before building to retain my old config settings.

I no longer have my vesa (framebuffer??) screen on boot.  The screen
is blank from after the lilo prompt until xdm starts.  In lilo.conf I
have vga=0x317 -- which is what I had before.

This is odd as I had this same problem (no screen at boot) when I
upgraded from 2.4.x to 2.6.x and resolved by rebuilding the kernel --
but I seem to have not written how I resolved it in my system notes.

It bothers me that a kernel upgrade from 2.6.5 to 2.6.9 with only a
few config changes would result in this problem.  Anyone have
suggestion what changed?

moseley@laptop:~$ egrep ^CONFIG /boot/config-2.6.5-xfs-toshiba > 2.6.5
moseley@laptop:~$ egrep ^CONFIG /boot/config-2.6.9-xfs-toshiba > 2.6.9
moseley@laptop:~$ diff 2.6.5 2.6.9
