I haven't been able to get bootsplash to work- i just found this section in /var/log/dmesg that tells me why

bootsplash 3.1.4-2004/02/19: looking for picture.... silentjpeg size 85519 bytes, found, but framebuffer can't handle it! (1024x768)

it looks like fb0 would work fine, so how do i get rid of fb1 and fb2?
