pcmcia with high mem support

Hi,

Recently I've got 2GB (2 x 1GB) RAM for my Dell Latitude C640
laptop. The spec. of the laptop says it officially supports
maximal 1GB (2 x 512MB), however the BIOS successfully
recognizes the 2GB RAM, and WinXP/FreeBSD5.1/Linux2.4/Linux2.6
all can use the 2GB RAM without any problems except that the
orinoco_cs driver does not work any more under Linux. (WinXP/
FreeBSD both can use 2GB RAM and the wireless card without any
problems).

The Laptop has a Dell True Mobile 1150 miniPCI wireless card,
which works fine under Linux 2.4/2.6 with the orinoco_cs driver
before I upgraded the RAM from 256MB to 2GB.

I use pcmcia-cs package (3.2.5 and 3.2.7). Before upgrading
RAM, the cardmgr program could probe and find the wireless card
perfectly. But now, it cannot find the wireless card at all.

Even though I specify the amount of memory to be 256MB as the
boot parameter when I actually have the 2GB installed, the
cardmgr still cannot find the wireless card.

How to solve this problem?

Thanks a lot for help!
