* hdparm -t reports 8.17 MB/sec at about 6% CPU usage for the DTTA
* - this is my first linux driver, so there's probably a lot of room
* for optimizations and bug fixing, so feel free to do it.
- * - use idebus=xx parameter to set PCI bus speed - needed to calc
- * timings for PIO modes (default will be 40)
* - if using PIO mode it's a good idea to set the PIO mode and
* 32-bit I/O support (if possible), e.g. hdparm -p2 -c1 /dev/hda
* - I had some problems with my IBM DHEA with PIO modes < 2

/* we don't check against CY82C693's min and max speed,
* so you can play with the idebus=xx parameter
