I used grub as my boot loader. When I boot up it gives me several different cheat code lines. One matches my display..fb800x600....i select that one and away I go. Thats it... You can also edit the cheat codes before booting with grub.

After you install, at rebbot, hit tab...

then type linux (or whatever the linux option was) and type:
vga=normal

so =>

linux vga=normal

and boot

The next step is different for lilo and grub

FOR LILO
open /etc/lilo.conf in you fav editor as root, and you will see the Linux title with stuff like
image = /boot/vmlinuz
root = /dev/hda1
label = Linux
read-only

put

append="vga=normal"

after it, save the file, and do

sudo /sbin/lilo

this will rewrite lilo to make vga=normal default

FOR GRUB
You'll have stuff like
title Linux
kernel (hd0,9)/boot/vmlinuz root=/dev/hda10
splash=silent desktop hdc=ide-scsi hdclun=0 showopts
initrd (hd0,9)/boot/initrd

put vga=normal after root=/dev/hXYZ

and then
sudo /sbin/grub-install /dev/hda
(change hda to whatever you got)

HOPE THIS WORKS

have fun, and experiment.

Alternativly you can boot into root and open
/boot/grub/menu.1st in beaver and edit it directly.
Be careful what you change though.

I see that you've solved it but thought I'd drop in my .02 anyway.
Add vga=xxx somewhere near the top of your lilo.conf file,open a command prompt and issue the command

Code Sample

dsl@box:~$lilo

reboot it should work every boot that way.

Heres an example lilo.conf file that works using this method with correct placement of the vga=xxx line
.
DO NOT copy paste this file. USE IT FOR REFERENCE ONLY as your setup is quite likely different than the one this conf file was generated for.

Code Sample

lba32 #enable large disk support
timeout=30 #wait 3 seconds before auto-booting
vga=788 #set screen dimensions and bit depth
boot=/dev/hda #put boot loader in MBR of target disk
root=/dev/hda1 #set root to be partition of target disk
image=/boot/linux24
label=DSL
initrd=/boot/minirt24.gz
read-only
APPEND="ramdisk_size=100000 init=/etc/init lang=us apm=power-off hda=scsi hdb=scsi hdc=scsi hdd=scsi hde=scsi hdf=scsi hdg=scsi hdh=scsi nomce nodma quiet frugal BOOT_IMAGE=/KNOPPIX/KNOPPIX restore=hda5 opt=hda5 home=hda5 dma mydsl=hda5"

Hope that was useful,
