I think ... This <Fn+Fxx> keys controled by SPIC(Sony Programmable I/O Control Device).
Download a picturebook application from
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.

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!).
