No pcmcia support confirmed 
Anyway, it can easily be enabled with loadmodule 
The Walker PCMCIA port might well be different from the A1200 so not too strange althogh something should likely be in the ROM to support it. I've always seen the Walker as a A1200 remake, especialy after seeing the PCMCIA port and A1200 style keyboard connecotr.
Was always under the impression the ROM was 1MB to fit in a few new things incl newer filesystem to support >4GB, SCSI.device and other mondified to support CD on boot?
Most disapointing is that it isn't WB3.2 installed.
