System is a Sony VAIO R505JE, kernel 2.5.3-dj1 + preempt + acpi + acpi 
pci irq routing.  Debian unstable, updated today.

1: USB dies a very similar death in 2.5.3-dj1 as it did in 2.5.2-dj6 
(OOPS below and in previous mail).  What else can I provide?

I hope these oopses were decoded correctly... ksymoops options used: -V 
-m /boot/System.map-2.5.3-dj1 -o /lib/modules/2.5.3-dj1/ --no-ksyms

2: Mouse issues still persist (missed one detection, haven't seen it 
slow yet).  I'm going to rebuild my kernel now with the latest ACPI 
patch and with the mouse input device as a module.  ACPI IRQ routing 
appears necessary to detect my mouse (not sure, but it seems that way) - 
does that even make sense?  Oh, and is there a way with a non-modular 
mouse input core driver to force it to re-scan the hardware?  Sometimes 
/proc/bus/input/devices doesn't show my mouse [so far I've been rebooting].

3: PCMCIA seems to have an issue.  Got a "socket cdcde800 voltage 
interrogation timed out" at bootup with my wavelan card (which only 
works with pcmcia-cs's wvlan_cs and neither wavelan_cs nor orinoco_cs) - 
this worked fine (slightly flaky, though - sometimes needed multiple 
"cardctl reset"s before it worked) in 2.5.2-dj6.  I don't know if this 
is a symptom of the kernel or just a chance with my card.  I will test 
further and report if it keeps acting up.
