I did some git bisecting during which I found it does matte wether you
let the drive settle before mounting or not during the 2.6.25 devcycle.
So after being struck at some random position I redid the bisection.
This commit applies to: changing the medium (cd/dvd), waiting until the
drive settles and mounting it. The kernel no longer changes the size of
the medium in /sys/block/sr0/size, giving read errors for bigger mediae.

[SCSI] sr: update to follow tray status correctly
Based on an original patch from: David Martin <tasio@tasio.net>
When trying to get the drive status via ioctl CDROM_DRIVE_STATUS, with
no disk it gives CDS_TRAY_OPEN even if the tray is closed.
ioctl works as expected with ide-cd driver.
