Subject: e100 fails, eepro100 works

Hi,
we have a couple of industrial PCs here with Intel PRO/100 controllers
on board. Most of them work fine with the e100, but today I stumbled
over one box that doesn't: Reception works (RX counter increases, ARP
cache gets filled up), but transmission fails (TX counter is also zero).
In contrast, the eepro100 is fine, also Etherboot's driver.
I'm currently on 2.6.17.8, but I don't see any changes up to latest git
that may have positive influence. This is what lspci -v tells about this
piece of hardware:
00:12.0 Ethernet controller: Intel Corporation 8255xER/82551IT Fast
Ethernet Controller (rev 08)
Subsystem: Intel Corporation: Unknown device 1229
Flags: bus master, medium devsel, latency 66, IRQ 10
Memory at fc020000 (32-bit, non-prefetchable) [size=4K]
I/O ports at 1080 [size=64]
Memory at fc000000 (32-bit, non-prefetchable) [size=128K]
Capabilities: [dc] Power Management version 2
And here is the kernel log of e100 with highest debug level when sending
out a few pings while other packets arrive on the network:

I may find the time one day to debug this at lower levels, but you could
accelerate this process with any pointer where to dig deeper precisely.
