I can't locate the correct firmware, the PSID reported by mtsflint 
corresponds to an Intel one:

Image type:      Failsafe
I.S. Version:    1
Chip Revision:   A0
Description:     Node             Port1            Sys image
GUIDs:           0002c9020022baa4 0002c9020022baa5 0002c9020022baa7
Board ID:         (INT0010000001)
VSD:
PSID:            INT0010000001

But I haven't been able to find any firmware in Intel's webpage.

Do you think that I could use a Mellanox firmware? Which one? There 
are three different ones for the MT25204.

I tried with 2.6.18 (the default etch kernel) and it gave the same 
problem.

Finally, I upgraded the BIOS of the machine (to version 85 from 79) and 
the module is loaded without problems and everything works correctly. So 
probably it was motherboard issue.
