IBM sells two AT types.  One is 6 Mhz, including the I/O channel, the other
is 8 Mhz, including the I/O channel.  Many of the "10 MHz AT clones" run the
processor at 10 MHz and the I/O channel at 6 MHz -- to be compatible with IBM.
What the expansion board would see would be 6 MHz in that case.

Of course, the expansion board companies may just not be willing to step up
to the 10MHz speed, given that *IBM* hasn't come out with anything faster
than 8 MHz.
