This is not possible since you need to use !HForm to alter the
RiscOS partition size. It could be done by altering all the disc
map and the like, but this would be *far* too complex.
For DOS there is a util lurking around which can be used to
repartition the harddisc without losing information, but I don't
recommend this.

The current problem is that the kernel polls (checks) the interface
every so often, to check if there is any pending data. This means
it does not use the interrupts generated by the card. The card
also supports DMA transfer, which is being worked on ATM.
Hopefully soon a kernel will appear with the relevant code in it.
