Yes we seem to be limited to 4GB mostly, with 3G mem hole, it's 3GB.

PPS: Today I had a brief look through your current sources. Look good
so far, except for a curious hunk which patches drivers/Makefile. And I
can't say anything to the x86 platform related and PCI related aspects

Hi,
I just wanted to let you know that I'll have picked up the early
firewire patch again and cleaned it up very much so that it should
be ready to submit it and but it on the patch-submission road.
What's left to do is to write some HOWTO like Stefan describes
below, but I'll try to get that

Some remarks to the September 2006 version at
http://www.suse.de/~bk/firewire/ :
- Seems its .remove won't work properly if more than one OHCI-1394
controller is installed. And it's .probe isn't reentrant, but that
