Is fixed in SVN revision r1239. Please use todays snapshot.
It was an unsupported GFP_DMA inside function get_sectorsize.
So the sr driver falls back to "capacity = 0x1fffff".

I have checked the Fedora 10 DVD image inside coLinux and all is ok now. :-)

debian:~# dd if=/dev/sr0 | sha1sum

7153464+0 records out
3662573568 bytes (3.7 GB) copied, 604.809 seconds, 6.1 MB/s

The DVD was configured in colinux config file as:
   scsi1=cdrom,\Device\Cdrom0
