THAT'S IT!

Very nice.. 30MB+/sec sustained for several minutes..
only 25% system CPU and the new profile is:

samples % symbol name
1047754 32.9054 pci_conf1_write
193876 6.0888 _spin_lock_irqsave
152897 4.8018 skb_copy_bits
74745 2.3474 _spin_lock
73273 2.3012 __copy_from_user_ll
69273 2.1756 __lookup_tag
65084 2.0440 _spin_unlock_irqrestore
43803 1.3757 sub_preempt_count
32047 1.0065 tcp_v4_rcv
30895 0.9703 schedule
26161 0.8216 kfree

Thank you!
