Booting ‘Debian Lenny’ into widescreen framebuffer

I have a Dell D630 Latitude(running Lenny) that i use at work. While trying to push the framebuffer size, i had to experiment a bit with numbers, because i couldn’t get ready to use values off google for widescreen framebuffers. ‘865‘ is what worked for me(it gives me 1280×800). If you got a widescreen laptop(i guess most laptops these days are), appending ‘vga=856‘ to grub boot line should make it come up in 1280×800 mode. For example, your kernel’s menu.lst(/boot/grub/menu.lst) entry should look like…

...
title           Debian GNU/Linux, kernel 2.6.26-2-686
root            (hd0,0)
kernel          /boot/vmlinuz-2.6.26-2-686 root=/dev/sda1 vga=865 ro quiet
initrd          /boot/initrd.img-2.6.26-2-686
...

Hope this helps someone. 😉
