Fix simple typos

In either case, the following conditions must be met:

- Quiesce all DMA capable devicess so that memory does not get

- Quiesce all DMA capable devices so that memory does not get

  corrupted by bogus network packets or disk data. This will save

  you many hours of debug.

  Although modularisation is supported (and required for the FP emulator),

  each module on an ARM2/ARM250/ARM3 machine when is loaded will take

  memory up to the next 32k boundary due to the size of the pages.

  Therefore, modularisation on these machines really worth it?

  Therefore, is modularisation on these machines really worth it?

  However, ARM6 and up machines allow modules to take multiples of 4k, and

  as such Acorn RiscPCs and other architectures using these processors can
