This sounds highly likely.  The Cisco 'stuff' they changed was probably
'portfast'.

See:-

	http://www.cisco.com/warp/public/473/12.html

for an explnation of why it can tkae upto a minute for a switch to start
passing packets after the PC has come up.  Also some (Cisco specific)
steps you can take (with detailed instructions) to reduce the problem.
[One of the steps is to twiddle duplex settings, but it's the very last
thing to try].
