+ * 22-Jan-2000 Moved camera init code to ibmcam_open()
+ * 27=Jan-2000 Changed to use static structures, added locking.
+ * 24-May-2000 Corrected to prevent race condition (MOD_xxx_USE_COUNT).
+ * 03-Jul-2000 Fixed endianness bug.
+ * 12-Nov-2000 Reworked to comply with new probe() signature.
+ * 23-Jan-2001 Added compatibility with 2.2.x kernels.
