Linus' tree is also broken.

I tried a Linus 2.6.24-rc4 and it acts the same way, with a very slow
transfer rate.  

I also tried 2.6.24-rc4 with the older not-libata PATA drivers and it is
broken.  dmesg had a line about the CF card detected as hda,
but /sys/block did not have hda and /dev/hda did not function.

I will try the patches you mentioned, but I think I may also have to
work backward through kernel versions until I find the last one where
the PCMCIA hd{a,b,c,d,e} drivers worked.
