It looks as if the root cause of the Dell PERC 2 issue is ACPI config-interrupts. I've been able to boot v2.6.25-rc8 with the kernel option "pci=noacpi".
I've got a bug open upstream:
http://bugzilla.kernel.org/show_bug.cgi?id=10396
a git-rev-list shows 277 commits to ACPI between v2.6.20 and v2.6.22 so it's going to be a big job to narrow it down.
