Comment 14 for bug 341094

lmpg, don't uncomment the kopt line. Leave it commented.

To activate the parameter you need to add them to the section below "End Default Boot Options" towards the end of the menu.lst file. Something like this below:

title Ubuntu 9.04, kernel 2.6.28-11-generic
uuid f2a9e7a4-a86f-43e2-85fb-baa9e860992c
kernel /boot/vmlinuz-2.6.28-11-generic root=UUID=f2a9e7a4-a86f-43e2-85fb-baa9e860992c ro quiet splash i8042.reset i8042.nomux i8042.nopnp i8042.noloop
initrd /boot/initrd.img-2.6.28-11-generic
quiet

Also you can add the parameters to the kopt option (but leave it commented) so that if they are regenerated (for example if you install a kernel update) the options will go in automagically. You don't have to take this step, you can just be aware and adjust as needed.
