As Charles already posted, idebus= is the PCI bus speed, and that
is 33 for _any_ i586 or higher system. See /usr/src/<kernel version>
/Documentation/ide.txt
As to hdparm, I found that with 8.2 and the default 2.4.18-6
kernel, any hdparm settings were ignored. ata/100 drives still ran
at ata/33. I found installing a newer kernel instantly fixes the
situation. I'm usin 2.4.18-13 and no hdparm or lilo settings. My
ata/100 drives run at udma5, ata/100, hdparm -t returns 40+mb/sec.
