I don't know if the issue is the same, I've just installed an 
HVR-1110 in a similar setup. It wasn't fully recognised in the 2.6.18 
kernel so I had to upgrade my DomU to 2.6.26 (Debian Lenny) which 
also required upgraded Xen to 3.2 using etch-backports (the Dom0 is 
Etch).

It now seems to work fine without anything other than the basic pciback.hide.
