PS: I tried to find out what is the companion chip in 54x, but I can't. "F1796" that hpcsh port page lists doesn't tell anything. There is a teardown report for 548 with all the photos at www.teardown.com, but it costs money to access.
If this web page can be believed: http://www.jonpeddie.com/dispatches/PalmShow/PalmDispatches.shtml
The 54x uses an Epson S1D13505 companion chip. Regards, Ross..
