Eli,
It turns out my main problem was that in the _farpokel and _farpeekl calls I 
was passing the linear address of the start of the descriptor (DUH!), rather 
than an offset into the segment referenced by the descriptor. There was also 
a problem with the descriptor buffer for the _dpmi_set_descriptor call.

Thanks for the help.
Jay

My apologies for not showing the register dump for the SIGSEGV. I looked 
into running SYMIFY but I didn't see a core dump to use with it.
