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,
  CJayC
