Running:

results in a bunch of missing lines of text once bootup finishes. Pressing enter a few times gradually fixes it.
I don't know whether this is a qemu bug or a Linux bug.
I'm seeing this on Fedora's 3.13.7 kernel and on a fairly recent 3.14-rc kernel. For the latter, cirrus is built-in (not a module), I'm running:
virtme-run --kimg arch/x86/boot/bzImage
and I see more profound corruption.
I'm guessing this is a cirrus drm bug. bochs-drm (using virtme-run --installed-kernel --qemu-opts -vga std) does not appear to have the same issue. Neither does qxl.
(qxl is painfully slow, though, and it doesn't seem to be using UC memory.)
