New Revision: 205647
URL: http://svn.freebsd.org/changeset/base/205647

Log:
  Fix stupid typos.  Some VESA BIOSes directly call BIOS interrupt handlers
  within the VBE interrupt handler.  Unfortunately it was causing real mode
  page faults because we were fetching instructions from bogus addresses.
  Pass me the pointyhat, please.
