> i need it if I want to support iSCSI (SCSI over tcp/ip)

James, 

I've modified the 2.6.7 Kconfig file to enable SCSI and SCSI_DISK
to be enabled even if PHYSDEV_ACCESS is not set.  A side effect
of this is that its now possible to select and build in scsi
low-level drivers in an build without PHYSDEV_ACCESS, which won't
work and will likely lead to people getting
confused. Unfortunately its not possible to fix this without
absolutely peppering the Kconfig files with gating on
PHYSDEV_ACCESS. 

BTW: I've had cisco iscsi 4.0.1.8 working fine with 2.6.7 without
modifications. We decided it was easier to workaround the issue
with ENABLE_CLUSTERING than get the change made to the iscsi
code. The workaround will probably help some other drivers too.

Ian
