* Version 1.0 ALPHA initial code, primary i/f working okay
* Version 1.3 BETA dual i/f on shared irq tested & working!
* Version 1.4 BETA added auto probing for irq(s)
* Version 1.5 BETA added ALPHA (untested) support for IDE cd-roms,

* Version 5.50 allow values as small as 20 for idebus=
* Version 5.51 force non io_32bit in drive_cmd_intr()
* change delay_10ms() to delay_50ms() to fix problems
* Version 5.52 fix incorrect invalidation of removable devices
* add "hdx=slow" command line option
* Version 5.60 start to modularize the driver; the disk and ATAPI
* drivers can be compiled as loadable modules.
* move IDE probe code to ide-probe.c
* move IDE disk code to ide-disk.c
* add support for generic IDE device subdrivers
* add m68k code from Geert Uytterhoeven
* probe all interfaces by default
