Bug#616389: xserver-xorg-video-radeon: Crashes when closing graphical VT ("(EE) RADEON(0): failed to set mode: Permission denied")

[Thue Janus Kristensen <thuejk@gmail.com>]

Googling a bit more, it turns out that the return value on amd64 is in $rax. That value was also -1.

"finish" doesn't display the return value, because there is no debug symbols. And amd64 assembler is not my strong point.

A random page on the Internet said that the return value is probably in eax. Doing 

> print $eax

after "finish" on drmDropMaster on the second X server, I get the value "-1".

Hmm, weird. Does drmDropMaster return 0, or an error code?
