Very Computer

I'm trying to configure XFree86 to disable key repeat on my
function keys (F1-F12), but not on any other keys.

Prior to making adjustments, xset reports:
    Keyboard Control:
      auto repeat:  on    key click percent:  0    LED mask:  00000000
      auto repeating keys:  00ffffffdffffbbf
                            fadfffffffdffdff
                            7f00000000000000
                            0000000000000000
      bell percent:  50    bell pitch:  400    bell duration:  100

Then I try:
xset -r 67 -r 68 -r 69 -r 70 -r 71 -r 72 -r 73 -r 74 -r 75 -r 76 -r 95
-r 96

Where the keycodes used are what "xmodmap -pke | grep F" reports as
belonging to the twelve function keys.

"xert q" then reports:
    Keyboard Control:
      auto repeat:  on    key click percent:  0    LED mask:  00000000
      auto repeating keys:  00ffffffdffffbbf
                            02c0ff7ffedffdff
                            7f00000000000000
                            0000000000000000
      bell percent:  50    bell pitch:  400    bell duration:  100

but, key repeat is still active on the twelve function keys!

Please help!

System info:
Linux 1.2.13
XFree86-Mach64 3.1.2E (ATI 264CT card)

Thanks.
