I have been using UDMA5/ATA100 for months, although this was set by a 
hdparm init.d script. Disabling the script, performing a cold reset and 
booting into a 2.6.21 kernel with the old ATA system enabled, hdparm -i 
indicated the HD was using UDMA5. I'm assuming that this means the old 
drivers do not limit to ATA33 unless there is a better I can check this.

I removed the laptop's hard drive. It fits into a cradle which is 
inserted into the laptop. There is no form of cable or adapter that is 
placed on the HD's connector. It just plugs directly into a socket 
inside the laptop when the cradle is inserted.

I hope this is enough information. I've included the output of dmesg and 
lspci -vxx.
