Not a lot faster if it is paging to disk during the install. I haven't 
used the sarge installer, but I recall that others reported even longer 
installs on macs without sufficient memory. I gather that installing with 
64 MB is OK.

You'll probably do better with the 2.2 kernel than 2.6 on the lc. But if 
you do try to boot 2.6.17, I'd be curious to hear the results.

As for the 540, the problem is the 68LC040. There was a thread on this 
problem (and 5xx powerbooks) a year or so ago on this list or the 
linux-m68k list. From that discussion I think we concluded that you must 
either disable swap, or else have a machine completely free of FPU 
instructions (e.g. a kernel configured with CONFIG_M68KFPU_EMU_ONLY, and 
userspace built with -msoft-float). But I don't know if anyone ever put 
that to the test.
