  *
  * An ATA driver to handle a Compact Flash connected
  * to the ixp4xx expansion bus in TrueIDE mode. The CF
  * must have it chip selects connected to two CS lines
- * on the ixp4xx. The interrupt line is optional, if not
- * specified the driver will run in polling mode.
+ * on the ixp4xx. In the irq is not available, you might
+ * want to modify both this driver and libata to run in
+ * polling mode.
