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...
