You should not need to change the bootloader to modify your screen resolution for a graphical application. Simply modify the guest's X11 configuration to change the size, as you would were the system not a virtual machine.

That said, unless you configure qemu to use the vmwarevga adapter (which isn't necessarily fully stable yet), only fairly standard resolutions are available; if you really intend to use 600x800 rather than the more standard 800x600, you may not be able to do that.

One failproof approach would be to start an Xvnc instance in the guest, and connect to that using a VNC client; this way, you can configure the Xvnc instance to any arbitrary screen resolution you like. If you use tap-based networking and are virtualized rather than emulated, it should also be quite a bit faster than other approaches.
