Now that a new -pre cycle is about to start, here is my latest
version of the sonypi driver.
The attached patch:
* fixes a hang problem when loading the driver on (at least) a
PCG-FX105k. Thanks to Jozef Kruger for reporting the problem
and testing different versions of this fix.
* tests if the ACPI subsystem is not disabled before trying to
use its ec_read/ec_write methods.
* fixes the hangs when enabling bluetooth (thanks to Daniel K. for
the patch).
* other miscellaneous small fixes.
Marcelo, please apply.
Stelian.

reproduce it on my laptop and not all users have this problem.
This happens because the fnkeyinit parameter enables the ACPI

speed handling etc). Use ACPI instead of APM if it works on your
laptop.
