[2.1.x] IDE interface probe oddity

Summary: idex=xxxx,xxxxx kernel boot options seemed to have changed.

I have a Promise Ultra33 addin board.
Epox KP6-LA Pentium II MB that has PIIX4 on board

As you will see from the boot up messages following, I can't specify all the
interfaces as I did with 2.0.32. In fact, they give BAD OPTION instead. (I
looked at ide.txt and didn't see anything about this new behavior)

2.1.89 (without options) will boot up and find the MB interfaces (assigning
ide0/1) and the Promise controller (ide2/3). This would work fine, but lilo
will then complain "can't handle device 0x2120". So this is what led me to
trying the idex=xxxx options.

2.1.89 (with options) works fine, but I'm concerned with the BAD OPTION and
the assignment of ide0 and ide3 being on the same controller but not grouped
together.

I'll gladly fill folk's e-mail boxes with boot messages and any other info
needed. :-)
