It depends...check the logs for driver messages, and look for a
low-level diagnostic utility for your NIC driver.  If you using Dan
Becker's NIC drivers, you can find several utility programs here:

You probably want mii-diag and vortex-diag...

NOTE:  This will tell you if you're half or full duplex ON YOUR END, but
not necessarily what you're attached to (the only info you'll get about
the far end is from auto-negotiation messages, if the far end supports
it, and even that could be mis-leading or wrong, since a lot of early
hardware didn't do auto-negotiation properly).  If your ISP's hardware
does not properly support auto-negotiation (highly likely, given your
description of the troubles you're having), you will have to find out
from them what you're hooked to, or make an educated guess by forcing
half and full duplex on your end, and seeing what sorts of errors crop
up.

I think the 2.4 kernels still have /proc/net/dev...
