Peter,

Not sure if you or Kevin builds the coreboot images at
http://code.coreboot.org/p/seabios/downloads/, but would you guys
consider building point release as well (e.g. 1.7.2.1), if yes then my
next question...

The rest of the ML,

Would qemu consider using those blobs rather than different developers
using their distro toolchain to build up a random commit ID. I say
random only because often qemu releases ship with a non-release
seabios.

In this past there's been other issues related to seabios + qemu, that
I've solved in Gentoo by simply using the coreboot seabios images
after some troubleshooting help from Peter. Similarly our Ubuntu
OpenStack machines at work had quirks resolved by dropping the
coreboot seabios images on them.
