That's my recollection also. The old Xorg from etch-m68k didn't require
mode switching.
I don't know if this behaviour is configurable in the current Xorg
(someone should consult the source code).
Arguably, macfb should support mode switching. No-one implemented it
because Apple never made public any DAFB chip docs.
Still, it's possible that someone has since figured out how the chip
works. NetBSD may have DAFB driver code.
BTW, if you do get Xorg to work in QEMU, you may run into ADB issues.
Those issues are being worked on.
Also BTW, if you have a Quadra/Performa/Centris/LC 630 or 580 or similar,
you'll find that the valkyriefb driver already supports mode switching.
