Ok, as said, I really don't see how it might depend on the max_baud_rate 
value in your case.

Ok, either race between irattach and the module-init or nasty interaction 
with hotplug stuff or similar. Maybe the module-init isn't finished yet 
when irattach ifup's the irda0 interface. The second time the module is 
already there thus no need to go thru the init path. I'm just guessing of 
course.

Please try something like
---
#!/bin/bash
modprobe ali-ircc
sleep 1
ifconfig irda0 up
echo 1 > /proc/sys/net/irda/discovery
---
instead of irattach. If it works, try without the sleep. If not, try to 
increase the delay. And please make sure you have CONFIG_IRDA_DEBUG 
enabled so you can check the syslog for suspicous messages.
