You are completely right on that, it is just that I thought those devices
didn't work on 2.4.33, but I just retested again and they work ok, only that
they were not working to me on the PC I tested the other day and it was
because of a nodev option :-) just that.

So... I have finised with my tests, I have tested an x86 client on which it
worked ok, just like on the PowerPC client, both working perfectly just like
they used to do on 2.4.33.

Maybe he had also applied some of the earlier patches you had sent and that
I did not apply to mine?

Just to clear things up a bit, I'm sure I'm with the 2.4.34 kernel and...
I'm running a pristine kernel with just this latest patch applied, the one
that changes S_IFREG for (fattr->f_mode & S_IFMT).
