Yeah, how about ditching the silly spec file patch mechanism, and use
something useful like a quilt series file instead?  Or at least add comments
to the spec file so that it is readily patched with AWK or Perl:

### ADD YOUR PATCHES HERE (20000 +) ###

...

### APPLY YOUR PATCHES HERE ####

Of course, the best solution would be to just include an ACPI DSDT patch
and taint the kernel, if the upstream developers don't want to deal with
the support issue -- that's why we have taint flags.  Let Intel spend some
of those "Intel Inside" marketing dollars to help the BIOS/mobo vendors
to fix the user experience; that ought not be our problem.
