ajax,
What do you mean by a pci revision id bump? Do you want it in qemu or the kernel? Why is a revision bump needed when none of the behavior of the cirrus device has changed?I agree that reading the BAR size from the device would be an enhancement. I'm working on the patch to include that now.

I was going to ask for a pci revision id bump at the same time, so the
guest could know.
I heartily agree, people should stop using cirrus. And qemu should stop
defaulting to it. Since neither has happened yet, enhancing the
emulation holds the promise of making the future better...
