5.4 RC3 fails to detect psm0. Normal except no PS/2 mouse. atapicam doesn't hang.

[Harry Coin]

5.4 RC3 as of yesterday fails to detect ps/2 mouse ( /dev/psm0) on 2 
different ASUS P4C800E boxes.  Dmesg follows.
5.4 as of a few days ago worked.

Normal functions otherwise so far as I can tell, it just doesn't load the 
psm0 driver.  moused complains.  So no X usability.

P.S. I wrote before about how these machines hung (interrupt storm) on boot 
with atapicam in the kernel on 5.4 but not 5.3.  atapicam does not cause 
boot problems any longer.  I don't know if it actually permits function, it 
failed to read sectors past 16K using 2048 byte block sizes in K3B.
