Back in the old days there was an upgrade set for the FastlaneZ3 so it would accept 16MB Modules too. That way the card could be upgraded to 256 MB RAM. AFAIK no one ever tested this setup, not even P5 themself, cos` that much RAM was quite expensive back then.
I have nerver come across such a "gold" Fastlane. there were very few of those upgradekits sold and 16MB 8bit RAMs are today even harder to find then 16MB GVP-Simms and more expensive to boot.

I for my part have a fully loaded DKB3128 und a normal Fastlane with 64 MB. Together with the 128 MB on the MKII my A3000T comes to a total of 320 MB of Fastram.
RAM on a ZIII card isn`t really fast, it only reaches 80-90 % the speed of onboard FastRAM.

Not really interesting, but it`s there.

4 GB like with the harddrives (remember 32bit), so we don`t have to worry about this border ever.

Sorry, but that won`t work, since the DKB3128 uses DMA and only 5 (or was it 6) of the slots are able to do DMA (like the commodoreguidelines stated), the others are non DMA. There were some Eagleboards that even had 8 Zorro III Slots.
I`m not sure how this ist handled, if there are up to 5 DMA-cards possible at once in any slot, or if simply Slot 1-5 can do DMA and the others don`t
