Linux 2.6.3 / cdrdao 1.1.8 only recognizes devices on one IDE channel

Linux 2.6.3 / cdrdao 1.1.8 only recognizes devices on one IDE channel

[Justin Piszcz]

The problem is cdrdao only see's the devices on the second IDE BUS (IDE1) 
and does not see anything on IDE0.

$ uname -r
2.6.3

$ cdrdao 2>&1 | grep -i version
Cdrdao version 1.1.8 - (C) Andreas Mueller <andreas@daneb.de>
