Odd, I have absolutely *zero* issues with Promise PATA cards...  I use 
strictly software RAID on both SCSI and IDE on Linux 2.4.  Never had issues 
with the kernel failing due to I/O load on rebuild or dealing with failed 
drives.

Note: You can easily throttle the I/O bandwidth used for rebuilding 
through /proc.  I've never had to do it though.

Now mind you all I do is software RAID1.  I don't do RAID5.  I typically buy 
drives in pairs and then use LVM to give me a big "blob" of storage and 
partition it up as I see fit with logical volumes.  The largest (# of drives) 
array I have is an 8-drive array, with 6 in pairs and ganged together for 
about 300G and then a separate RAID0 on a pair of old IBM DeathStar drives 
for my temporary data area for MythTv.  This is all on a cheapass Pentium3 
system.  No issues even when running in degraded mode.
