ACPI and USB support -CURRENT on a Sharp Actius um32w

[Aditya]

I'm running -CURRENT on a Sharp Actius um32w last cvsupped on Sep 28
at 9:25 PDT.

An account of what works and doesn't is at:

  http://www.grot.org/laptop/sharp_actius_um32w.html

this is a nice small, light, thin laptop with lots of stuff built in,
however ACPI support is hardly out-of-the-box good...nothing surprising!

S5 works, and S1 doesn't. S3, S4 although they put the machine to
sleep, and there is activity when you wake it up, don't seem to wake
up the display.

Any hints on improving the ACPI support would be much appreciated.

Also, the USB causes a page fault when copying the *second* file from
a umass device (a camera in the case I tried) -- the first file is
fine oddly enough...

Thanks,
Adi
