Here's the full, restructured patch. There are two remaining issues
with it
that I'm not sure how to deal with:
1) It'll probably break ia64 and ppc builds.
2) On all ATI cards I tested the font loading code on so far there is
a
(hardware) flaw that doesn't permit loading the font into other than
font
slot zero; the code, however, defaults to load the font into slot 2,
which
means that on ATI cards this currently only works with an additional
command line option "fontslot=0". The purpose of loading into slot 2
is
to preserve the (BIOS provided) font in slot 0 (perhaps slots 0 and
1),
as would Linux do if it didn't set BROKEN_GRAPHICS_PROGRAMS
(almost) unconditionally (in include/linux/vt_kern.h).
