it was exactly the same for me (was time-consuming to figure out).

However, with kernel 2.4.18 this problem just disappeared. A good soul named 
Michal Ceresna (his credits here) sent me a patch as feedback to an 
installation report I published via www.linux-on-laptop.net:

That's it:

*** maestro3.c  Fri Mar  1 11:18:58 2002
--- maestro3.c.org      Fri Mar  1 11:16:03 2002
***************
*** 2236,2242 ****
  
      for(i = 0; i < 5; i ++) {
          dir = inw(io + GPIO_DIRECTION);
!         /*dir |= 0x10;*/ /* assuming pci bus master? */
  
          remote_codec_config(io, 0);
  
--- 2236,2242 ----
  
      for(i = 0; i < 5; i ++) {
          dir = inw(io + GPIO_DIRECTION);
!         dir |= 0x10; /* assuming pci bus master? */
  
          remote_codec_config(io, 0);


As you can see, the changes are minimal. With the stock 2.4.18 kernel this 
patch was already integrated; now it does not matter in which order the irda 
modules or maestro3 have been loaded. It just works..

Don't have tested any FIR devices, either.

Regards,
	Frank
