SubjectNS83820 2.6.0-test5 driver seems unstable on IA64

I'm having some problems with the NS83820 driver on Itanium-1.

1. I see many many `unaligned accesses' when the IP header is
accessed (ip_input.c:410 and 423)
It looks as if the IP header is two byte aligned, when it ought to be
4-byte aligned.

The error message is, e.g.,
kernel unaligned access to 0xe000000128d8881e, ip=0xe0000000047ba2d1
0xe0000000047ba2d1 is
if (iph->ihl < 5 || iph->version != 4)
goto inhdr_error;
0xe000000128d8881e is what's calculated as &iph->ihl
The obvious approach of realigning the SKB by 2 bytes seems not to

Any ideas?
