This still isn't fixed?? We had a fix in hand _months_ ago. That's the only
way that we could get an EV6 system with a SYM adapter (like almost all of the
ones that Compaq sells) to work correctly. I don't know who dropped it or how
it got dropped, but I know that Jay had a kernel with a work-around at about
the same time as RH shipped 6.0. I believe the fix Andrea pointed to is
correct - if we're still seeing those problems, we should make sure this is
merged into the base code.
