You can just make it a platform device I suppose. In the meantime...

Maybe set ISA_DMA_THRESHOLD somewhere? Some platforms seem to set it:

./platforms/52xx/efika.c:       ISA_DMA_THRESHOLD = ~0L;
./platforms/amigaone/setup.c:           ISA_DMA_THRESHOLD = 0x00ffffff;
./platforms/chrp/setup.c:       ISA_DMA_THRESHOLD = ~0L;
./platforms/powermac/setup.c:   ISA_DMA_THRESHOLD = ~0L;

So if anybody knows another way around this? The driver is basically
allocating a scatter gather list that is passed to a DMA engine in the
FPGA.

This isn't a showstopper.... we are not planning to move to 2.6.30 in
the near future.

Can't you set ISA_DMA_THRESHOLD = ~0L from your warp.c platform file ?
