Probably not a real Alice in there, just something (FPGA) that reports looks just enough like an Alice chip to get the OS to boot... The ram therefore is just regular ram tagged as chipram... 
The chipram reported is the memory on the RTG card (a modified retina 3). The DraCo booted from an A3000 kickstart ROM with a load of patching done at boot.
It contained no real custom miggy chips.
