Here's the list of stuff nero (and/or some libs) tries to open in /dev  
/proc and /sys:
---snip---
/compat/linux/dev/scd0
/compat/linux/dev/scd1
/compat/linux/dev/scd2
/compat/linux/dev/scd3
/compat/linux/dev/sg0
/compat/linux/dev/sg1
[... upto sg9 ...]
/compat/linux/dev/sr0
/compat/linux/dev/sr1
/compat/linux/dev/sr2
/compat/linux/dev/sr3
/compat/linux/dev/urandom
/compat/linux/proc/66876/stat
/compat/linux/proc/ide/ide0
/compat/linux/proc/ide/ide1
[... upto ide31 ...]
/compat/linux/proc/meminfo
/compat/linux/proc/scsi/scsi
/compat/linux/sys/block
/compat/linux/sys/devices
---snip---

Now we need to investigate what linux is having at those places and  
what is needed to emulate it (only text output, or ioctls, ...).  
Anyone with a linux system and appropriate hardware out there who is  
able to post examples?

Without an example we can not emulate...

When I look at the list of files nero tries to access, it's not a  
surprise that it doesn't see it. We do not emulate the necessary ide  
stuff.

I don't remember to have seen something on the emulation@ list. If  
there would have been something, I would have reacted the same as for  
you (kdump + analysis).

Bye,
Alexander.
