Gentoo boot issue, possibly framebuffer?

Hi,

I've been installing a Gentoo system for the last few days (off and  
on), and I just got it setup the way I want, except that now it won't  
boot correctly. I recompiled the kernel and tweeked some settings,  
and now when I try to boot the first few lines of the kernel flash  
by, but then the monitors flash off and give a warning that the  
display signal is not compatible.

At this point, I can press Ctrl-Alt-Delete and restart, but the  
computer does not seem to be booting up normally, because if I wait a  
few minutes, I still can't ssh into the system.

I'm sorry I can't give more detail, the kernel logs flash by so  
quickly I can't even tell what the last thing displayed before the  
screen goes black is.

Any thoughts?

I've tried passing:

video=vga16:off in to the kernel at boot time using grub, but that  
doesn't seem to help. :(
