I can confirm the problem, using today's fully updated Jaunty + virtualbox-ose-guest-utilities 2.1.4-dfsg-1ubuntu3 in guest, so it is still a problem with the newer vboxvideo driver.
Additional info: when I run 'xrandr' in the guest, I get:
miki@miki-virtualbox:~$ xrandr -q
Screen 0: minimum 64 x 64, current 800 x 600, maximum 32000 x 32000
VBOX1 connected 800x600+0+0 0mm x 0mm
800x600 60.0*+
640x480 59.9
so it seems that the supported resolution range is huge, but only those 2 modes are actually defined.
