A00 came installed and is the latest.

This one is different, but like you said sata failing seems to be a
symptom and not the cause:

0000:00:1f.2 IDE interface: Intel Corporation 82801GB/GR/GH (ICH7
Family) Serial ATA Storage Controllers cc=IDE (rev 01) (prog-if 8f
[Master SecP SecO PriP PriO])
        Subsystem: Dell: Unknown device 01ae
        Flags: bus master, 66Mhz, medium devsel, latency 0, IRQ 20
        I/O ports at fe00 [size=8]
        I/O ports at fe10 [size=4]
        I/O ports at fe20 [size=8]
        I/O ports at fe30 [size=4]
        I/O ports at fea0 [size=16]
        Memory at 40000000 (32-bit, non-prefetchable) [size=1K]
        Capabilities: [70] Power Management version 2

I just noticed the hypervisor leaves a message on the screen:

(XEN) *** Serial input -> DOM0 (type 'CTRL-a' three times to switch
input to Xen).
(XEN) (file=.../xen-unstable/xen/include/asm/mm.h, line=201) Error pfn
6000: rd=ffbfb080, od=00000000, caf=00000000, taf=0000000c
(XEN) Domain 0 shutdown: rebooting machine

Thats with dom0_mem=98304. The pfn number changes: 128MB reports Error
pfn 8000, 512MB reports pfn 20000. I guess the next step is to run it
under a debugger and try to get a back trace from that error?
