I use grub, so I use the vga= kernel parameter. The equivalent in lilo
would be:
append=" vga=788"
You can find out what framebuffer driver you are using by looking at the
output from dmesg.
(BTW, I genuinely don't know whether the vesa framebuffer driver is
supposed to be able to interact with the /dev/fb[0-9] devices - there
might be a kernel bug in this regard.)

You'll have to edit /etc/inittab so that it actually uses /sbin/fbgetty
instead of /sbin/getty (because /sbin/getty isn't an alternative the way
most substitute packages are - it's a real binary because it's so
essential to getting the system up and running). You'll also want to edit
/etc/issue (after looking at fbgetty's manpage) because its placeholders
there are different.
