[Wine] Problems with NX ?

[voidcreature at paradise.net.nz]

i've just compiled and installed 0.9.7 on my shiny new pentium D box 
(FC4+updates & 2.6.15.1 kernel)

and i've got a pesky solitary windows application that page faults at it's 
entry address (0x406796).

its only this one application that dies (its a proprietary compiler, so i 
can't distribute anything to test with unfortunately).

if i turn off NX in the BIOS, it works fine with no other changes.

using wine-preloader has no positive effect

is there anything i could/should be doing? anything i should change in the 
compile process?

thanks.
