Read the correct error status register on SBus cards. 

Don't set infinite burst on SBus cards.
Changes based on information in the `Sbus GEM Specification':
  http://mediacast.sun.com/users/Barton808/media/gem_sbus-1.pdf

SBus-based GEM cards (i.e. Sun X1140A) now work!
Tested with a X1140A card in a U1 and in a U2.
Thanks for martin@ for testing.
