We seem to be seeing the same failure on a Dell Poweredge 860 with their SAS 5/IR RAID card which I think is just a rebadged LSI.
(There really needs to be a defined way of stuffing update modules into the existing install CD; for example, hypothetically, imagine that one of these machines was 4000 miles away on the other end of a IP-KVM and you'd asked someone over there to put a dapper server CD in and you want to do the rest. Hypothetically speaking it would be a pain if there was no neat way to fix the fact that the kernel on the install CD couldn't cope; for a LTS solution this is important).
