How to add noapic to grub?

Upon booting in Feisty 7.04 on an AMD64 PC, I get the error message:
[ 79.123557] ..MP-BIOS bug: 8254 timer not connected to IO-APIC

There is discussion on the forum that adding noapic to the boot sequence will eliminate the problem. Please tell me exactly what words to add and exactly where in the sequence to add them?

Very important: What bad side-effects will occur if this work-around is implemented?

If you need to do it just to get the system up then when the grub screen comes up hit the E key. Then you have to hit it a second time. Down to the kernel line and at the end place the word noacpi. Hit B key to boot the kernel.

To make permenent then edit /boot/grub/grub.conf and place at the end of the kernel line. like you did on boot. Save and exit.

Example of the kernel line.
kernel /vmlinuz-2.6.23.1 ro root=/dev/sda9 rhgb quiet noapci
