Pro/100 + Linksys router problem

Hi,

Is it known whether the Pro/100 PCI card (or at least the version in 
Dell Inspiron 8000 laptops) has a problem autonegotiating with the 
Linksys BEFSR41 (wired) router?

I've found (both in Windows & Linux with eepro100) that if the card is 
allowed to autonegotiate it *appears* to negotiate 100/full duplex 
successfully, but there seems to be a duplex-mismatch (many packet 
collisons, etc.). If the card is forced to half duplex then a successful 
connection results - again both in Windows & Linux.

The card autonegotiates correctly directly with my (cable) modem and 
other NICs (in other PC's on the LAN) autonegotiate ok with the BEFSR41. 
Cabling & router LAN ports all check out ok.
