Ah, yes, ... :-) Try emm386 without the VDS argument and under no circumstances run FreeDOS FDISK unless you want to risk an erased partition table.
OK I ran the tests again, after taking out VDS everything is working normally, FDISK /INFO reports the correct partition sizes and luckily my computer still works (I'm typing this message on it).
Regarding LBACACHE TUNS, it's exactly the same as under UMBPCI, it's loads high with no problems and no timeouts. Below is the memory map and the FDCONFIG.SYS
