It would be nice to see this bug in my installation. But, it does 
running without problems for me.

My coLinux config:
colinux-daemon -t nt mem=64 kernel=vmlinux ^
  cobd0=Debian-4.0.img root=/dev/cobd0 ^
  cofs0=. ^
  scsi0=cdrom,\Device\Cdrom0

"\Device\Cdrom0" is a Fedora 10 install DVD. This I used to checksum the 
read via scsi driver.

Under Linux was running:
debian:~# dd if=/dev/sr0 | md5sum
27e581edb392728c4a07d00d3fc5ced0  -
7153464+0 records in
7153464+0 records out
3662573568 bytes (3.7 GB) copied, 797.93 seconds, 4.6 MB/s

But, have not your messages in kernel logs.
debian:~# dmesg | grep -E 'sr|sd|scsi'
scsi0 : Cooperative Linux SCSI Adapter
scsi 0:0:1:0: CD-ROM            coLinux  COCD             1.01 PQ: 0 ANSI: 2

My used coLinux was the last snapshot from 
http://www.colinux.org/snapshots/ :
debian:~# dmesg | head -n1
