I guess/claim that the support people of my provider don't know that and it would cost me a fortune to confirm this suspect. But if I'm right, you say with the clamp rule the problem is solved (seems to by dynamic then) and I don't need to know at all? Any idea why this was no problem with kernels < 2.4.20 (only wondering, not a need to know)? By the way, I found the number 1430 a couple of times in different other maillists to be the size always working with the Alcatel Speedtouch USB, I have no idea about a technical background of exactly that size.
