After my patch the hvm domUs start correctly with both cirrus and stdvga 
with all upstream qemu versions (I tested up to 1.6). Without it the hvm 
domUs was unable to start in some case with qemu 1.3 and all case of 
qemu >=1.4.

If I remember good I did fast test with qemu traditional with my patch 
and was working with both vgas, the only case (but I not completely 
sure) is with qemu-trad and cirrus vga where 4 mb of videoram could be 
unused IF cirrus support only up 4 mb.
