If this one hadn't mentioned it.

Argh.  Could we please be better with the changelogs?

This one tells us briefly what the patch does, but it deosn't tell us
why it does it.  It doesn't tell us whether it fixes some bug (and if
so what that bug is) and it gives me no means of determining whether
the patch is needed in 2.6.26 or in 2.6.25.x.

Ditto pnp-set-the-pnp_card-dma_mask-for-use-by-isapnp-cards.patch
