Comment:

 I agree w/ Rob that we can and should rebuild certain key packages (glibc,
 perhaps even python and other main interpreters) with geode optimization.

 They should mix and match fine, and shouldering the burden of building a
 few packages might be worth it; the rest can certainly come prebuilt from
 upstream until there is a Geode-targeting Koji build server.

 When does Rob return from conference?  What should I do in parallel
 that'll help but not duplicate his effort?

 Shall I try building us a gcc 4.2.2 compiler with the geode patches from
 4.3?

 From what I can see of the geode-gcc-4.2.patch on gnashdev.org, it does
 not do anything for the two new geode-specific 3dnow instructions, which
 include the very useful inverse sqrt.  Shall I take a look to see if it's
 in gcc 4.3 at all, and try my hand at pulling it into the patch, or adding
 a peephole optimization for it if it isn't supported in gcc yet?
