Thanks for that Steph,

This is what I now get:
conor at charzard:~ $ sudo hdparm -t /dev/hda

/dev/hda:
 Timing buffered disk reads:   86 MB in  3.06 seconds =  28.13 MB/sec

Much more acceptable. 6MB p/sec was painfull.
Why did I not have to re-create the initrd though, I am confused
about that one!
