I don't think is an hardware problem.
1) Please try unplugging the serial mouse from IOBlix and tell me what
happens
   reloading the driver.
2) Using 2.2 kernel what was your configuration ?
   Was you able to use a serial mouse a with that kernel & IOBlix
driver?
3) Do you use the IOBlix Ethernet module with Linux ? and if yes with
what type
   of driver?
Taking a look in the flow of kernel's IPL the serial devices are
configured before 
the ethernet ones  and when the driver initialize the serial part of
IOBlix is a MUST 
to keep switched off all the interrupts this because there is a risk to
make
false UART starts. Unfortunately AFAYK there are only three bits i can
use to 
disable interrupts and are listed in the ioblix.h file.

Thank you for your response
