Yep, the message could be misleading wrt to the probe_mask. Is something
along the lines of

"please adjust the probe_mask module parameter for probing the rest of the
legacy ISA IDE ports"

more informative? Now it implies that the primary/secondary ports are
probed by default.

However, you still have to set it to something > 0x3 if you want to
probe ide[2-5]. Also, there's still the option of CONFIG_BLK_DEV_GENERIC
which adds support for otherwise unsupported IDE PCI controllers.
