Yes..... Finally got OS3.5 running on my A500 (CSA MMR 68030/68852 33mhz, GVP HD8+, 1mb Chip, 8m Fast, 2.5m 32-bit Fast). It's got 2.04 ROMs softkicked to 3.1 and it kept blowing up after the 3.5 install.
I found that the SetPatch supplied with 3.5 installs some updates then reboots.... thus erasing the softkicked roms.
Solution was to use the Setpatch40.16 that comes with OS 3.5 (as opposed to plain SetPatch), combined with RemLibrary from the emergency disk.
As I understand it, the patches that cause the trouble are for scsi.device and FFS to support volumes over 4gb, which I don't have anyways.
User review of 3.5:
Mmmmm pretty.
