 That appears to be more helpful than I would have expected.
 
 It looks like stable/8 includes r233791 of 2012-04-02 which is described 
 as:
 
     MFC Revision 233465
 
     Correct failure to attach the PV block front device on Citrix
     XenServer configurations that advertise the multi-page ring 
 extension,
     but only allow a single page of ring space.
 
 Sounds promising, and the small change (only to 
 sys/dev/xen/blkfront/blkfront.c) was not MFC'd into RELENG_8_3.
 
 Looks like my next step will be to switch my csup tag to RELENG_8
