Is it worth considering writing an 'ata' driver that doesn't support
old devices, but leaving the existing 'wd' driver there for systems
that need it?

I presume the wd driver contains two sets of cludges, those for
broken (or old) controllers and those for broken (or old) disks.

Dunno how you sort out the kernel config though :-(

Is there a driver for non-dma devices?  The code paths are much
cleaner is you don't have to do DMA - especially for memory cards
where there is little point doing reads asynchronously.
