Thanks. There may be more to it than what I suspect, but I could not
reproduce it on x86_64.

Now I may have missed something as I optimized my tested based on the fact
that close and open are triggered when you up and down a network interface.
so I didn't do a complete rmmod, (since my network driver wasn't modular).

Since you have seen this on x86_64 I will look deeper.

gah, strike that.

my only x86_64 system here survived the test with latest git tree.

my 386 system here has no msi devices and I can't reinstall my x86_64 system since it's headless, so I can't test anything until monday. I'll give it a full test again and see which 2.6.20rc kernels did fail, most likely a much older tree (I suspect).
