Fine.

We are unlucky. This means that GPIO is controlled not via standard
AC97 register, but somehow via MMIO and now we will need to find this
"somehow" (GPIO bits manage DAA interface, including 'Hook-Off' switch,
unfortunately the modem is completely useless without it).
I've looked at win driver
(ftp://ftp.asuscom.de/pub/NOTEBOOK/L8400B/Audio_Modem/8baudw9x.exe)
and think (after few 'strings' runs) that 'ASP4_CTL.vxd' is softmodem
driver (I am completely unfamiliar with .inf files, so please correct
me if I am wrong). Nothing interesting until now and looks that this
file was not dissassembled there
http://savannah.nongnu.org/cgi-bin/viewcvs/openvortex/plato/
Do you or anybody have idea how to dissassemble *.vxd file? (I would
prefer with linux :)).

This will not help anyway.
