I did.
Although I have to admit I did a bit spoppily since I did most tests with my 
635.

The error is only in the comment in the config file.
The code (CFontzPacket.[ch]) is correct.

Ill correct the comment in LCDd.conf.

Interesting: My CFA-631 has both 2.0

The CFontzPacket driver is not doing any cross checks.
So you might succeed if you set
	Model=633
	Speed=115200
	Size=20x2

I had issues with my USB CFA-63[135] too.
I solved them by calling ./configure with the following command line
	CPPFLAGS="-DSEAMLESS_HBARS -DCFONTZ633_WRITE_DELAY=250" \
	./configure ....

The 1st one of these two flags makes the full hbar element 6 pixel wide
so that a hbar does not contain any gaps
The 2nd flag changes the functions in CFontz633io.c so that select() is when 
waiting for a command, that was sent to the LCD, to complete.
This makes sure the LCD is ready before the next command is sent.
(You might want to look at the code to see the exact details)
I chose to make it optional to not disturb the serial CFA-63x

With these options my 635 works flawlessly for months now.
