I didn't quite get that...

1) What is "less effective results" and why you are so excited about
them?
2) What did you use: the 2.0.38.0-990914-990930 patch or
   2.0.38.1pre1-vag tarball? I told you to use the latter (i.e.
tarball),
   since they are totally different.

What kind of image are you using: RAM or ROM based? (looks like ROM).
Do you compile it using "make FLASH_LOAD_ADDR=0x10000 flash.b" and
then load using bbug and tc_flash.b? Please, make sure that tc_flash.b
has the appropriate preamble.

Please, check the baud rate that is set during the serial driver
initialization in 68328serial.c uCsimm sets it to 9600 and my
boards use 115200. If you use my bbug you'd better use 115200 too.

Well, "make clean" wipes out all .o and .a files ...

On a more productive note: send me your diffs and I'll try to take a
look.
To make this process even more productive, make sure that the schematics
you have on the web is the latest one.

Happy hacking,
Vladimir
