You need gcc272 for 2.2 (and 2.0 if you really want to try that) kernels. I
built 2.4 with gcc-2.95, but I heard for some people 3.2 or maybe even 3.3
is working too.

If you want vanilla, get the source from the linux-m68k CVS. The
debian kernel-source package contains quite a few fixes. The m68k
kernel-patch package basically gets you back to linux-m68k CVS, I am in the
process of changing that, I have a much smaller diff (for debian's
kernel-source-2.4.20), but I haven't tested it yet, so I don't know if I
erased too much. Now if you try 2.0, 2.2, or 2.4, or maybe even 2.5, is
really up to you. With Debian 3.0 you might have troubles if you try a 2.0
kernel. 2.2 should work since most of the build machines run that (2.2.20,
or the "new" 2.2.25). 2.4.20 runs very well on my Amiga:

 10:51:10 up 25 days, 11:31,  4 users,  load average: 1.73, 1.79, 1.73
cts@aahz:~>uname -a
Linux aahz 2.4.20 #1 Thu Apr 24 23:19:55 EDT 2003 m68k unknown

And I don't plan on going back. If you want to hep linux-m68k, you should
probably give 2.5 a try and supply patches.

You mean vga textmode is supported by the CV3D (ie virge) driver? Now that
is news too me, too bad that my CV3D died... but I am still taking donations
