Subject: #define bswap_32 bswap32 for NetBSD in the mach64 driver; also, for
 the sis driver, use either NetBSD's atomic ops if we have them, else check
 for gcc's __sync_synchronize.  I suppose the right thing to do is split the
 dri drivers out of this package, but hopefully this will resolve [pkg/39359].
  No revision bump, as I just updated the package a few hours ago.
