FWIW, I've tried FreeBSD as an HVM guest on several Linux distros as 
Dom0, Xen 3.0 (3.0.3, 3.0.4) and 3.1 (3.1.0), using Xen packages and 
manual compiles.  Linux distros included Ubuntu 7.04 and Debian 4.  
FreeBSD 6.2 and 7.0 -- release and snapshots -- consistently fail to 
boot with a looping "BTX halted" and register dump.  If there's a way 
to install stock FreeBSD under Xen HVM, I haven't seen it.  Without 
saying whether this is properly a Xen problem or FBSD BTX problem, my 
guess is this type of installation will not work until there are BTX 
changes.
