Comment 79 for bug 362582

I try to give it a shot again but I'm still blocked at the same point I was last time, running X -verbose with a couple of added debugging message, I get:

=========================================

I still don't understand why the driver can't read in ns2501_dpms function while it works elsewhere in the code. Also, I tried to find iegd sources but could only find binaries and I had a look at desassembling it but I'm really a n00b at that. Please help me understand the problem.
