I neglected to mention that the above patch (exactly the same, as it
turns out :-)) is how I forced the ide-proc.o build.  The brokenness
extends deeper.

Specific example: proc_ide_read_geometry has the requisite EXPORT_SYMBOL()
wrapper in ide-proc.c, yet, I still end up with proc_ide_read_geometry_R*
unresolved at depmod time.  In case anyone is wondering, I *did* do a
"make clean", manually cleaned out linux/include/modules to make *sure*
there wasn't any old cruft lying about, then ran "make dep && make bzImage &&
make modules && make modules_install".  The depmod output quoted below is
the result of all that.
