My guess is that you just don't have the appropriate framebuffer drivers 
configured in "Device Drivers->Graphics Support".  With the Gentoo 
sources, I recommend at least CONFIG_FB_VESA=y and 
CONFIG_FB_VESA_TNG=y.  If you do you will need to change your boot 
options, as VESA_TNG doesn't use the vga= parameter:

kernel (hd1,2)/boot/linux-2.6.12-gentoo-r6 root=/dev/hdb3 
video=vesafb:1280x1024-16@60,ywrap,mtrr pci=usepirqmask
