OK, your IDE channels appears to be on these sysfs paths

 /sys/devices/ide0
 /sys/devices/ide1

which is strange; normally it would appear as a child of a PCI device,
e.g. on your second box it is at

 /sys/devices/pci0000:00/0000:00:1f.1/ide0
 /sys/devices/pci0000:00/0000:00:1f.1/ide1

and this is what triggers what is apparently a bug in hal. 

So, what we do today is to say "if the IDE device is not a child of a
PCI device, then it is definitely something we can't poll on". Instead,
the logic we apply is that we should poll on IDE, if, and only if, the
device is an optical drive. And we can check that.

Please try the attached patch (against the hal 0.4.x branch in CVS;
should apply to 0.4.2 as well) to see if that makes it better? 

I will go ahead and test that it works with other IDE devices such as
Zip drives and Memory card PCMCIA readers.

Thanks,
David
