Yes, I still have the hardware and I created a second fresh Fedora 10 
system on my Pismo, without any changes in the configuration etc.

So the kernel version is 2.6.27.12-170.2.5.fc10

The only thing I manually did was:
rmmod firewire_ohci
modprobe firewire_ohci debug=7
modprobe firewire_sbp2

(firewire_core is also loaded)

firewire_ohci gave the following in the kernel log during modprobe:
Feb  8 19:23:26 *** kernel: firewire_ohci: Added fw-ohci device 0002:24:0e.0,
OHCI version 1.0
Feb  8 19:23:26 *** kernel: firewire_ohci: IRQ 00010010 selfID AR_req
Feb  8 19:23:26 *** kernel: firewire_ohci: 1 selfIDs, generation 1, local node
ID ffc0
Feb  8 19:23:26 *** kernel: firewire_ohci: selfID 0: 807f8c52, phy 0 [--.] S400
gc=63 -3W Lci
Feb  8 19:23:26 *** kernel: firewire_ohci: AR evt_bus_reset, generation 1
Feb  8 19:23:26 *** kernel: firewire_core: created device fw0: GUID
003065fffe3f9f74, S400

When plugging in my external FW drive I get repeatedly from firewire_ohci:
Feb  8 19:26:04 *** kernel: firewire_ohci: IRQ 00000010 AR_req
Feb  8 19:26:04 *** kernel: firewire_ohci: IRQ 00010000 selfID
Feb  8 19:26:04 *** kernel: firewire_ohci: AR evt_bus_reset, generation 2
Feb  8 19:26:04 *** kernel: firewire_ohci: 2 selfIDs, generation 2, local node
ID ffc1
Feb  8 19:26:04 *** kernel: firewire_ohci: selfID 0: 807f8490, phy 0 [p-.] S400
gc=63 -3W L
Feb  8 19:26:04 *** kernel: firewire_ohci: selfID 0: 817f8cd2, phy 1 [c-.] S400
gc=63 -3W Lci

and from firewire_core:
Feb  8 19:26:04 *** kernel: firewire_core: phy config: card 0, new root=ffc1,
gap_count=5
...
Feb  8 19:26:34 *** kernel: firewire_core: giving up on config rom for node id
ffc1
Feb  8 19:26:34 *** kernel: firewire_core: phy config: card 0, new root=ffc0,
gap_count=5

The last message (changing sometimes from root=ffc0 to root=ffc1 and back) and
the firewire_ohci messages are repeated until I remove the FW device. No
message from firewire_sbp2. 

Does anybody have an idea?
