== Current Issues ==
 * The Ricoh SD card reader is not recognized (kernel 2.6.17-11-generic). This is a kernel/acpi issue and is being worked on.
 * I need to reload ipw3945 if I boot with the wifi switch off and want to use it afterwards (1).
 * Gnome cannot set the screen brightness (but the keyboard switches work) (2).

=== Notes ===

 * (0) I have the English keyboard, this Vaio being released for Japan only as of today 2007-03-07, the default keyboard layout is Japanese.

 * (1) Wireless
I installed ipw3945d by hand from http://packages.debian.org/unstable/net/ipw3945d by copying it into /usr/local/sbin and wrote the followin startup script. 

/var/log/acpid reports

when switching off (SPIC ... 3d) and on (SPIC ... 3c) the big wireless switch on the computer.
Hence, if I find how ACPI is dealt with in Ubuntu, I will get the switch to (un)load the module and start/stop the daemon as needed.

 * and the hardware switch works for both wireless and bluetooth (the switch works, I have not tried BT).

 * (2) Current screen brightness is shown at /proc/acpi/sony/brightness; there also exists a /proc/acpi/sony/brightness_default. Maximum/defaults value is 8 (and I like 6).  However
