Odd.  Can anyone confirm dualhead works on the XPRESS chips with the
radeon driver?  Support for them was added kind of by trial and error
(no info from ati).  They may require some special handling for
dualhead.  Also, if the XPRESS chip are anything like the older IGP
chips, they may only have one DAC.  I think we treat them as if they
have two at the moment.  You may want to set the info->HasSingleDAC
flag in the driver and recompile and see if that helps.  Can you
confirm dualhead works with fglrx?  If so can you get a dump of the
regs with radeontool under fglrx and the radeon driver?
