Here's the gsKit debug output. I removed the output from init code for IOP drivers and from FCEUltra internal stuff. It doesn't look that helpful.

I went through using WinMerge on the disassembly output on gsCore.o. I compiled gsKit with the same cygwin ps2sdk, but with the different toolchains. I'll list the first block of changed assembly. The first paste is Cygwin and the second is Mingw. 1a0: is where the changes start occurring.
