The pst (promise supertrak) driver is utterly not 64 bit clean.  It uses a 32 
bit space in the I2O control blocks to point to the freebsd driver data 
structures.  Since the freebsd kernel lives at the top of the 64 bit address 
space, this does not work too well.

Yes.

The SX6000 is the pst driver above.  It might not be *that* hard to update it, 
but if you ask Soren (sos at freebsd.org) very nicely, he might take a shot at 
it.
