I've finally received a new S3992 based server yesterday.
I've been hit by 4 issues and here they are:

1.
The one thing that was clearly lacking from Tyan and ThermalTake was that 
there are actually 2 different Heatsink sizes on the market for Socket F 
systems. Some heatsinks at 3.5" and others at 4.1".

ThermalTake's Socket F heatsinks use 4.1", while the Tyan board uses 3.5".

In the end I got 2 Socket 940 heatsinks using the special brackets from 
Tyan.

After rereading the specifications, the only line that was a clue to is 
was "Uses the standard 3 1/2"/89mm socket connector" which is really not 
telling much.

2.
The second issue was that when I disable the "Hide XIOAPIC PCI functions" 
the linux kernel will only see 1 core of 1 cpu. My only clue to that being 
the problem was a post to the Linux Kernel List from someone that had the 
same problem but mentionned he couldn't remember what setting he used.

3.
If the fan fail led is enabled, then not connected fan are marked as 
failed and there is no way to tell it to ignore them. The bios will also 
give a message like "FAN5 RPM doesn't detected".


4:
lm_sensors require a special program to "switch" which set of fan and cpu 
is being monitored. I really wish that there is a way to avoid that. I 
like being able to parse the output of lm_sensors to hobbit (aka big 
brother) for monitoring purposes.
