Nope. No fb anything in /dev.

I haven't rolled my own since my gentoo days. I run 2.6.26-2-686. It looks
like yours but for CONFIG_FB_BOOT_VESA_SUPPORT, which is not an option at
all. Not that it's not set - it doesn't exist in the kernel. If you look at
Joel Roth's post, it doesn't seem to be in his, either, and he's facing the
same problem. Is it that config that generates the fb*?
