I think ... This <Fn+Fxx> keys controled by SPIC(Sony Programmable I/O Control Device).
Download a picturebook application from
 http://samba.org/picturebook/
and make it.
and check with this command...
 # capture -j
then press <Fn+Fxx> keys. May be you can see the press event...
Here is a event data...
 <Fn+ESC>  : event 0x10 0x29  &  event 0x10 0x28
 <Fn+F1>   : event 0x11    ------ same -----
 <Fn+F2>   :       0x12
    :                :    <F3> -> <F11> : 0x13 -> 0x1b
 <Fn+F12>  :       0x1c
 <Fn+"1">  :       0x21
 <Fn+"2">  :       0x22
 <Fn+"B">  :       0x35
 <Fn+"F">  :       0x33
 <Fn+"E">  :       0x32
 <Fn+"S">  :       0x34
 <Fn+"D">  :       0x31

Recompile the your Kernel with "Enable console blanking using APM" option.
then the backlights off.(only text console)
I checked Kernel 2.2.17,2.2.18 & 2.4.2

My VAIO could(can) go into suspend mode....but never wakeup.
as same as APM case.

addition....
You can use the internal USB-Memory-Stick device with Kernel 2.2.18 and usb-storage module. and the sound module is ymfpci.
take care about ymfpci module... because, some time I get a NOISE!!!
in this case just shutdown(not reboot!).

Thanks
