I've run into this problem with some concentrators.  

See if it implements "link integrity", which made its way into the 10BASE-T  
spec in Feb 1990 (according to the change page I have here).  If not, it won't  
work and you may be due a free upgrade if they promised you a  
10BASE-T-compliant product.

Some concentrators also have an "automatic rollover" feature which switches the  
T/R pairs when they've been connected backwards (but you say you've checked  
that...).

Thanks to the network managers at NeXT Redwood City who helped me when I ran  
into this myself...
