Okay something really bizarre is going on, it may be two separate issues. I went back to kernel 2.6.16-1.2122_FC5 and 2.6.16-1.2111_FC5, and once again jack apps would segfault on startup. I determined running jackd at a period of 256 somehow was causing this, even though I *swear* it was working at one point. Backing off to 1024 worked fine.
Going back to kernel 2.6.17-1.2139_FC5, and running with a period size
of 1024 allowed me to run hydrogen for a bit, but when I quit hydrogen I
still got this:

The madwifi drivers are tainting my kernel, for some reason they keep
getting loaded even if I don't plug the card in. Though I've been
running madwifi this whole time so I doubt that its the problem. I'll
try nuking them entirely off my system. ;P
