We should get a newer version stable. I got some error with 0.7 not being able to decode the the buffer. Newer versions seem to work.
x86: Please stabilized app-admin/mcelog-1.0_pre3 the current stable version doesn't work with kernel 2.6.31
Forgot to add x86
It passes the tests here on x86 and seems to work with 2.6.32.
x86 stable, thanks Andreas
