Hi JeffBonn,
I just made a new iso file using the same grub binaries and boot mechanism as Kanotix
which I hope will work better for you. This iso contains the the official KNOPPIX 4.02 release
with a patched initrd boot ramdisk to fix the USB 2.0 and persistent ext2 problems
and add some extra features as custom (and dynamic) hostnames, ...
http://s94002264.onlinehome.us/grub/iso_usb2.iso (md5: 147b03e54ad4b2260b015b041391cf4b)
One more time, this is just for demo and test purpose, so please let me know when your download is done
and obviously what is the result of your test.
Best Regards,
Gilles

PS: I used the following command line for the generating the iso file:
#!/bin/sh
mkisofs -pad -l -r -J -v -V "KNOPPIX_usb2" -no-emul-boot -boot-load-size 4 \
-boot-info-table -b boot/grub/iso9660_stage1_5 -c boot/grub/boot.cat \
-hide-rr-moved -o ../iso_usb2.iso .

Thank you Gilles, it works! hdparm -t shows that my hard drive and
my memory key are both running at their correct speeds. The grub menu
is different from regular Knoppix, but the "e" command let me add
the home=/mnt/sda1/knoppix.img cheat code.

Also, thank you for providing the exact mkisofs command. This will be
helpful if I try to do my own further customization.

I hope that Klaus will include your fix in the next release.
