Does it work for you in polling mode?  If not, you probably have a
problem with the way you are accessing the system ace - cache,
endianess, byte alignment, etc.  If it does work in polling, the usual
suspects are interrupt masking errors or some low level problems with
your IRQ signals.  Since you know the size of a sector and the size of
the sysace buffers, how many interrupts do you get per sector read?  Do
you see extras or not enough?

Dump the sector data to the screen that you are reading from the CF.
Especially look at the results from the initial identify command to
verify that they make sense, and because that is the easiest to check.

Shouldn't this be /dev/xsysace1?  You want to mount a partition not the
entire block device.
