"You are at Witt's End ..."
Well, I am. Parallels 8.0.18608. Mac OS 10.8.5. Plan 9 from roughly August 30. 9pcf kernel running flawlessly in a 2560x1440x32 full screen window, for weeks.
Two days ago, I boot the VM and it (9pcf) decides there is no longer a frame buffer. It worked fine the day before. I haven't touched any of the Plan9 binaries or kernels, nor have I (knowingly) updated Parallels. I did do the Mac OS 10.8.4 -> 10.8.5 update recently, but I am positive this worked after the OS upgrade.
I have had this happen before with Parallels, and have never been able to discover the underlying cause. And it is driving me completely fscking insane. Someone please tell me I am not the only one being inflicted with this. Or better yet, come exorcise the bad bloody hardware karma I am suffering! I don't deserve this ...

Yes, and aux/vga shows all the VGA BIOS entries I expect to see.

does "aux/vga -l $vgasize" do what you expect?

No, it actually kicks the display into graphics framebuffer node. (That's *not* what I expected.) But this turns up a new problem: no data from the mouse. /dev/mouse is there, but it returns no data. I can start rio at this point, but without the mouse it doesn't do a whole lot ...
I will continue to tinker ...

due to the second law of thermohorification, fixing one thing means that at
least one other thing goes broken. perhaps your mouse:parallels connection
kept the universe's hork in balance.

Whatever it is, it's very bizarre.
The aux/vga in termrc isn't running. The one I added to $home/lib/profile is. (And why isn't 'flag +x' added to /rc/bin/termrc barfing out the expected trace data? The 'echo kill -roy' immediately below it fires off.)
A second look at the pci output shows that nothing behind the USB bridges is being detected. This explains the absence of a mouse. But changing the plan9.ini mouse setting from intellimouse to ps2 solves that for now.
If we were a couple of weeks closer to Hallow'een, I would buy in to this. As it is, it's just spooooky ...

at least on my machine, the simplified relevant bit looks like
if(test -f /dev/mousectl && ~ $mouseport ps2 ps2intellimouse 0 1 2 usb){
if(! ~ $"monitor '' && ! ~ `{cat /dev/user} none)@{
run vga from in here
}
so if yours is similar, which one of the follwing is false?
1. test -f /dev/mousectl
2 ~ $mouseport ps2 ps2intellimouse 0 1 2 usb
3. ! ~ $"monitor ''
4. ! ~ `{cat /dev/user} none
could /dev/user be none, while $user = your user?

If the 'flag +x' worked as documented, it would be easy to tell :-p
I will printf my way through it tomorrow. Tonight I am going ignore it and burn a steak ...
