Are the cx88 drivers supported on the AMD-64 platform?

Can I use a Hauppauge 1800 on a system running on amd-64 with more than
4 GB memory, or do I need to run in i386 mode?

Yes. The 1800 has a 64-bit DMA engine, so it can be used with > 4GB
with no performance penalty.
The older 32-bit cx88 cards are also supported on large-memory
machines, but their DMA routines may use double-buffering.
