1581 burst/fast serial does not work on c128 #216

If you test Pi1541 with Krill's loader test (builds directory!) on c64 and c128 with both 1541 and 1581, I get the following results: -c64 with .d64: Fails after quite a while (for me it was run #275) with the error msg "safety margin exceeded" -c64 with .d81: Seems to work fine, I stopped after 400 runs... -c128 with .d64: Fails after about a minute with the error msg "safety margin exceeded" -c128 with .d81: Fails right at the beginning with "wrong load address"

Now, I'm not sure if my 2.4A USB-PSU is to blame for the endurance test failures (I ordered a 3A one specifically designed for Raspi and will amend the report if it's any different with that!), but since the .d81 fails on c128 right at the start, I'm quite positive it's lacking burst/fast serial/2Mhz support in the Pi1541...

Tried the 3A PSU, exact same behaviour... Only .d64 on c64 does seem to fail a bit earlier, but I feel that one is rather random!...
