It is, depending on how you look at it, either a guest X issue or the 
lack of a choice of monitors to emulate in qemu.

If you add "-std vga" then a Windows guest will immediately let you 
select a resolution of at least 1600x1200 but a Linux guest will not - 
you will have to go and add that mode to xorg.conf to get it.

If you look at the X log in a linux guest you will see it tried to DDC 
probe the monitor, got no result, so fell back to a couple of fairly low 
resolution modes as defaults. There is then no way to force that other 
than by manual editing of the configuration.

So possible fixes would be to add more modes to the defaults that X 
uses, or to make qemu respond to the DDC probes with some sort of 
emulated monitor information.
