You didn't read that error message well enough. :)
(in fact, maybe it's not your fault, but the massage is a little bit
missleading...)
idebus doesn't set UDMA speed, it sets the system bus speed that is
used in ide timing calculations. From ide.c:
/*
* ide_system_bus_speed() returns what we think is the system VESA/PCI
* bus speed (in MHz). This is used for calculating interface PIO timings.
* The default is 40 for known PCI systems, 50 otherwise.
* The "idebus=xx" parameter can be used to override this value.
* The actual value to be used is computed/displayed the first time through.
