Just for the record, no, read the fine print: (It's in the mac section of that FAQ you pasted the link to) you still can't run regular Linux on an original 68020 LC after adding an FPU because the LC also lacks a 68851 PMMU and there's no straightforward way to add one. (IE, no socket, unlike the original 68020 Mac II.) It's mildly interesting how the FAQ says there's a "hardware hack"; if there's a way to add a PMMU *other* than upgrading the CPU to a 68030 or better it seems to be rather difficult to find a reference.
