[SOLVED: PARTIAL] Laptop display goes wonky during boot

Hello. I recently installed grub on my Toshiba Satellite M30 laptop. When grub loads with its splashscreen, everything is fine, but after the OS is selected and I get about a page of output from Gentoo, something changes in the display. My font looks choppy and cutoff, and I'm getting a wrapping/duplicating display problem.

What should see is

that's a framebuffer issue.
have you tried something along the lines of what the handbook implies to do with vesafb? I know that at least with my nvidia on my amd64 the tng doesn't work and all drivers except that one need the vga statement, the video statement with resolution will not suffice.
this is working fine for a geforce 6600gt and only vesafb compiled in: vga=0x31B video=vesafb:mtrr,ywrap

Thanks!

Turns out, I had two framebuffers running, the nvidia, and the vesa. Once I removed the nvidia from my kernel config, the vesa took over and worked properly. After much experimenting, I can't get the kernel to take mttr or ywrap. I haven't noticed any major performance issues yet; however, I also haven't finished setting up xorg-x11. When I set mttr and/or ywrap, all the text gets squished into the lower left quarter of the screen, and after scrolling about 40 lines, the system just feezes and I'm forced to hardboot. Will I experience slowdowns without these two options?
