kbit means 1000, Kbit means 1024:

http://www2.computer.org/portal/web/publications/styleguidejkl
http://en.wikipedia.org/wiki/Kilobyte
http://dictionary.zdnet.com/definition/kilo.html

Modem data rates such as 14.4, 28.8, and 56k are 1000 bits per second.
Ethernet data rates such as 10, 100, and 1000 are powers of 1024, but
"baud" doesn't usually come up in that context.

As you can see from the above links, style guides vary.
