Qlogic ISP1020 in 2.6?

I've got an Alpha (COMPAQ Professional Workstation XP1000) with a
built-in ISP1020. Kernel 2.4.28 runs fine on this system; 2.6.9 gives
me the following errors:

ERROR: SCSI host `isp1020' has no error handling
ERROR: This is not a safe way to run your SCSI host
ERROR: The error handling must be added to this driver

Googling for this has shown a fair number of other people with similar
problems, but I've not found any mention of somebody working on
this. I'm happy to take a look myself, but I thought it might be
useful to check here first before I wade in. Anybody?

Try using the qlogic 1280 driver instead (thanks to Christoph and I think
Andrew V), I have these in my .config:

# CONFIG_SCSI_QLOGIC_ISP is not set
CONFIG_SCSI_QLOGIC_1280=y
CONFIG_SCSI_QLOGIC_1280_1040=y

That last one is really for both 1040 and 1020 support.

The queue depth is overly deep (255), I think because there is no firmware
and/or nvram support, I haven't figured it out, but I don't generate a lot
of IO on them.
