FireWire + Apple PB G3: some success

[Albrecht Dre_]

[I am new to the FireWire list, so please excuse me if this is not new for you.
Sorry, this is a quite long message]

I had some success with Newer Tech's FireWire2Go CardBus device on an Apple
PowerBook G3/333 (aka "Lombard") with LinuxPPC 2.2.14pre9.  This is what I did:

* added Ryuichi Oikawa patch to the kernel which enables the pci scan to "see"
CardBus devices without the PCMCIA package (there is a japanese description at
http://www.rr.iij4u.or.jp/~roikawa/others.html [which I can't read], but the
patch seems to work really fine)

* used the FireWire package for 2.2.14.  As always with LinuxPPC, I had to patch
the pcilynx driver, as OpenFirmware (Apple's "BIOS") does not activate all
devices automatically:

* `modprobe pcilynx' gives the following kernel messages:

kernel: ieee1394: registered pcilynx driver, initializing now
kernel: pcilynx: looking for PCILynx cards
kernel: pcilynx0: allocated interrupt 0
kernel: pcilynx0: allocated PCL memory 65536 Bytes @ 0xc12f0000

kernel: pcilynx0: resetting bus on request

* remaining questions:

I have a FW disk attached to the bus, but when I run testlibraw, it is not seen:

[root at tirilap133 src]# ./testlibraw
successfully got handle
current generation number: 0
1 card(s) found
  nodes on bus:  0, card name: pcilynx
using first card found: 0 nodes on bus, local ID is 0

doing transactions with custom tag handler

using standard tag handler and synchronous calls
[root at tirilap133 src]#

Is this normal, or where ist the problem?

Thanks, Albrecht.
