Hmmm..., I just followed the installation handbook. Plain, unmodified kernel configuration, which has framebuffer support enabled.
At the chapter of configuring grub, it mentiones that using the framebuffer was optional.

If you have configured your kernel with framebuffer support (or you used genkernel's default kernel configuration), you can activate it by adding a vga and/or a video statement to your bootloader configuration file.

I tried some kernel parameters in grub.conf:

video=vesafb-tng:mtrr,ywrap,1024x768-32@85
Still stalls.

video=vesafb-tng:mtrr,ywrap,1024x768-32@60
Because I read in a mailing list about vesafb not being able to switch refresh rates (might have been an old mailing list)
Still stalls.

video=vesafb-tng:1024x768-32@60
Removed the mtrr and ywarp in case they were not supported.
Still stalls.

video=vesafb:1024x768-32@60
In case 'vesafb-tng' is not supported but 'vesafb' is.
Still stalls, but messes up the remaining text on the screen.

In the mean time, I have done the same install in VMware.
That install boots (succesfully!) with the "video=vesafb-tng:mtrr,ywrap,1024x768-32@85" setting!! (Although in 640x480, but that's caused by VMware).

So my conclusion is that there is something with my hardware configuration.
I'm using a VIA Epia ME6000 Mini ITX board.

I had Gentoo 2005.0 running on this board, so maybe something changed in this area between 2005.0 and 2005.1?

When I boot this board with the Gentoo 2005.1 LiveCD, it seems to use the framebuffer.
The isolinux.cfg mentions "vga=791", but that doesn't seem to solve my problem as well.

-nofb , as suggested by Michael Kintzios, did not help.

Thanks for the help so far...
