On the 68LC040 software FPU emulation errata...
For those who wonder when Motorola started producing 68LC040 processors without the errata that caused problems with software FPU emulation, here is the actual PCN right from Freescale:

Cool - thank you. It's good to have a link like that which people can find easily.
I'd also like to remind people here that NetBSD for m68040s with no FPU (no matter which mask) compiled with -msoft-float is available here:
ftp://ftp.mac68k.org/pub/NetBSD/5.0.2/mac68k-softfloat/
and binary pkgsrc packages, also compiled with -msoft-float, are available here:
ftp://ftp.mac68k.org/pub/pkgsrc/packages/NetBSD/m68k-softfloat/
The binary packages are being built on a 40 MHz Quadra 605 and are updated daily, so the list will continuously grow. Currently we're up to 238.
