it needs the plan 9 c compiler, but
it's not actually the kernel that's at fault here: aux/vga is
a user-level program, and it's in the bzip'd file
system on the diskette.    i've put a modified diskette image that
might work on http://www.vitanuova.com/ndisk.gz;
you'll need to replace plan9.ini by the one you've been using.

Should applying this patch enable one to install on a system using a
3dfx Voodoo3 2000 AGP card? I was having problems starting rio.

Since I don't have a successful installation yet to recompile from, is
there any way to make this change to the kernel of the installation
boot floppy? Can the Plan 9 kernel source be recompiled with GCC under
FreeBSD or Linux or does it require the Plan 9 C compiler?

Thanks,
