[PATCH] misc fixes

- unused var warning in pnp_add_irq_resource()

- unused var in fd_mcs.c (Adrian Bunk)

- remove dead code in i810_main.c (a u8 cannot exceed 255) (Adrian Bunk)

- don't truncate dma_addr_t's in gdth.c (Jes Sorensen)

- vgastate.c needs vmalloc.h (Geert Uytterhoeven <geert@linux-m68k.org>)

- revert bogus test from rd_open() - it was a 2.4 forward-port, and 2.5
  doesn't need it.  (The gendisks aren't registered, we cannot get there
  anyway).
