802.11g mini-PCI for Tecra S1

I've come into possesion of a Tecra S1-009Y2 and I would like to fit an 11g
mini-PCI card. Toshiba AU tell me that the only compatible card they have
is PA3266U-1MPC, but this is only 11b. I asked about the PA3298U-1MPC or
the PA3300U-2MPC and they say they may work, but Toshiba hasn't tested them
and is unlikely to do so in models it no longer sells.

So has anyone got a 11g mini-PCI card working in a Testra S1-009Y2 ? My
understanding of the 009Y2 is that it is a Pentium M - 1.4 and has an
internal antena but no card.

Thanks
