Hello Hannes,
Patch applies well to qemu tree and with a one line modification to
qemu-kvm.
My testcase was to install Fedora 16 x64 on qemu-kvm. Unfortunatly
it was NOT successful.
1.) Strange thing is that udevd got into timeouts and tries to kill
a lot afterwards.
2.) Report that udevadm settle - timeout of 120 seconds reached, the
event queue contains: ....
3.) Then it hangs in Examining Devices ...
Looks like that hd device is dead.
With LSI 53C895A everything is fine and install works well.
Any ideas?

MSI-X support is buggered, and due to a bug in megasas.c you cannot
switch it off :-(
