Hi again,

Phil, according to this:

http://www.ibiblio.org/peanut/Kernel-2.6.10/scsi/ChangeLog.megaraid
(note the kernel version)

The PCI id's for the i4 have been added to megaraid

Release Date	: Fri Jul 23 15:22:07 EDT 2004 - Atul Mukker <atulm at lsil.com>
Current Version	: 2.20.2.0 (scsi module), 2.20.1.0 (cmm module)
Older Version	: 2.20.1.0 (scsi module), 2.20.0.0 (cmm module)

ii.	Add PCI ids for I4

Considering the date, I imagine that this change was old enough that it 
would have been included in RHEL4.

So I've got a tentative green light for support.  I'll be making a bid, 
but it looks like this auction is being populated by newbie's as the 
price seems to be heading up rather quickly, especially considering what 
the card actually is.

The PCI and device ID's:
1000 0522  MegaRAID 522 i4 133 RAID Controller
