Hi,
Just a heads up that WINE seems to suffer from breakage if executed as a 32bit binary on an x86-64 kernel as of 2.6.17-rc, because (according to Andi Kleen) i386 NX is now enabled by default, and on x86-64 i386 behaves like a PAE enabled i386 kernel when performing IA32 emulation.
I've attached the entire thread for reference, as unfortunately I do not have the time to debug this problem, but thought that probably one of you would like to know.

Andi suspects that WINE is not making one of its mappings PROT_EXEC which causes a fault with NX enabled.
Well, in your case it seems to be the main executable, since it faults at its very first instruction.

And look for the virtual entries in the vicinity of 495000.
