Just a bit of confirmation:

Since mid-2004, the large motherboard manufacturers noticed an increased 
complaint ratio with motherboards equipped with ICH5. A cause was the 
insufficient ESD tolerance of certain ICH5 steppings.

In particular, when connecting USB devices via front panels, the chips died by 
discharges of static electricity. Intel reacted to the problem by shipping 
ICH5 with increased ESD tolerance. Effective ESD preventive measures on USB 
ports are difficult and costly, since they can impair signal quality of the 
USB-2.0 high-speed signals. Many motherboard manufacturers had omitted the 
necessary high-quality safety devices for front panel connectors for cost 
reasons.

By the way ICH6 has similar problems.
I have about 70+ dead P4 mobo's in the basement - almost all with southbridge 
dead.
