Hmmm I'm running 2.2.14 with latest Promise driver from their site.

Raid 5 running just fine.

Bleah, why?  I haven't figured why there are all those IDE-SCSI hiding
things yet.  The history of Linux seems to point towards the IDE support
being better than the SCSI, and yet the CD-R/W devices work through the SCSI
interface, and it looks like now the disks will.  Obviousally, I don't keep
up on all of the kernel developments, I've still got a full time job to keep
track of, but I'm still interested.

What you do not know is that there will be a drive int the futre that
will have a native SCSI overlay and front end.  This will have a SCB->ATA
converter/emulation.  This will require setup and booting as a SCSI
device.  FUN, heh??

Yo Andre!

I know that, I am using Mingo's RAID-1 patch.  Sort of figured that
should be obvious on the linux-raid group...

RUDE surprize for you

Hardware RAID 1 under promise is not hardware!

Details.drives and host bios rev (promise)?

Yo Andre!

2.2.14 did not work for me.  I have a dual PIII with onboard UDMA33
controller running RAID1.  Very stable.  When I just moved the
two drives to a Promise Ultra66 the system became very unstable
(uptimes in minutes). YMMV.

Yes PDC20246/PDC20262 are SMP safe.

I can't tell you about the SMP support, but the driver is NOT included
in the standard source tree.  You need to get your hands on the IDE
patch from "The Linux IDE Guy".  All his work is included in the 2.3.xx
and should be in the 2.4 kernel (much like the RAID).  

This card has worked well for me, but I have yet to try it in a
software RAID. Using the "new"RAID patches.

Check out the patch, there are at least 2 other cards.
