I don't have the debian sarge source handy, but the kernel.org 2.6.8
kernel's drivers/scsi/megaraid.[ch] driver indeed does not have the
PCI IDs for these controllers present.  Looks like I misremembered
when I put that text on linux.dell.com, I've corrected it.

kernel.org 2.6.9 drivers/scsi/megaraid/megaraid_mbox.c  does have the
PCI IDs for this adapter.

Right, this are the right IDs, as your working 2.4 scenario shows:

> megaraid: found 0x1028:0x0013:bus 2:slot 14:func 0


so your 2.6.9 kernel should work.

Thanks,
