I guess another option would be to temporarily stick a compatible SATA card 
into the machine but I understand that wouldn't be ideal!

If you were to use a Linux distro with Xen included then they have often 
forward ported Xen support to newer kernels.  Fedora and OpenSUSE do this, 
for instance.  Also RHEL / CentOS contain backported drivers from newer 
kernels, so it's possible that one of them would work on your system.  Ubuntu 
contains Xen-enabled kernels newer than 2.6.18 also, but I've heard varying 
things about the quality of Ubuntu's own Xen packages - though I haven't 
tried them myself.

I think it's still based on 2.6.18 so the same probelm applies.

I'd say that using a distro with good Xen support is your best bet.
