Do not forget that FW is very powerful. Likely the parking feature was added after A6BA. Basically I saw that the only difference between me and Pekka was the FW (discounting the different CPU speed and Kernel version). I googled around and found the IBM FW page at: http://www-306.ibm.com/pc/support/site.wss/document.do?sitestyle=ibm&lndocid=MIGR-41008 Download is simple, just don't use the "IBM Download Manager". Main problem is that one needs a bootable floopy drive and "the other OS" to create a bootable floppy. It would be great if IBM could provide floppy images for use with "dd" for the poor Linux users. Then I pondered over the risk involved with the update. Curiosity won :-) And now the head parks. BUT - I definitely do not encourage anybody to perform the procedure. Do at your own risk after thinking about the possible consequences ... Anyway someone reported a non working HTS548040M9AT00 with FW revision MG2OA53A. The newest revision, from the same floppy image, is A5HA.
