Networking :: ndiswrapper memory allocation

Hi i am using a Linksys WPC11 v4 wireless card with ndiswrapper. The drivers are the recommended RealTek ones. When the computer (toshiba 1555CDS) starts up, it modprobes ndiswrapper. I get the following error:

ndiswrapper (NdisMAllocateSharedMemory : 997): Failed to allocate DMA coherent memory. Windows driver requested 2042 bytes of cached memory. Windows driver could not initialize the device.

Any suggestions?
