Actually, it's 'modprobe ir-kbd-i2c hauppauge=1', but it's not necessary if 
you create a custom keymap.

Shouldn't be necessary.  As previously stated, create your own keymap.  The 
ir_rc5_decoder module should decode all RC-5 codes, it's mapping them to 
keycodes that's the issue.

No.  No lirc at all.  ir-kbd-i2c with RC-5 enabled as the protocol will allow 
you to pass keycodes directly to the OS (or any application) without running 
an lirc daemon.  With the proper keymap I just emulate all "normal" key 
presses as if the remote is a keyboard.  So "p" is play, "i" is info, "enter" 
is select, "m" is menu, etc.  See the keymap file I previously posted.  If you 
download and compile v4l-utils (since the package is not available for F14) 
you can set a custom keymap and the remote should send the correct keys.  This 
assumes you set the non-standard IR codes I have on my remote, but at least 
the number keys should work without making any changes.  I could probably dig 
up the others I use if I needed to.  Or you could use the defaults and
'ir-keytable -t' to see what scancodes are sent by the default IR codes for

Me too!  ;-)
