gig network again

I recently bought my gig network hardware:

netgear GS605 switch
2 Tredware PICTX nics

The only thing I didnt replace are the calbes.  ethtool shows both new 
nics at 1000/full duplex.  Here's the problem.

time dd if=/dev/zero of=/home/daz/udaz/testfile bs=32k count=32768
32768+0 records in
32768+0 records out
1073741824 bytes (1.1 GB) copied, 371.025 seconds, 2.9 MB/s

real    6m11.180s
user    0m0.020s
sys     0m5.820s

When I switch back to my 100M switch:

time dd if=/dev/zero of=/home/daz/udaz/testfile bs=32k count=32768
32768+0 records in
32768+0 records out
1073741824 bytes (1.1 GB) copied, 437.263 seconds, 2.5 MB/s

real    7m17.364s
user    0m0.028s
sys     0m10.113s

So, the question:  Will my kernels negaotiate a 1G connection if the 
cables are not gig qualified?   If not, then I need to look at something 
other than the network hardware (unless I just got really crappy 
equipment).

Thanks,
David
