It seems so far. There hasn't been any problem since I've applied the fix.

For the record: this HTP374 is running with a quite outdated firmware (1.22) - maybe newer firmwares work correctly. I'm going to upgrade the firmware to the latest one (which was released in 2004...), but unfortunately in the upcoming 2-3 weeks I won't have access to this machine, so I can't check the case within the release cycle of 2.6.22. If you were interested I would post the result of the firmware upgrade.
