Well, the "ft232r" programmer is not meant to be a full-featured
programmer for everyday work.  It abuses the FT232 as a bit-banger
with a very slow protocol.  The main intention for this is to allow
for e.g. programming an initial bootloader into a device connected to
it, where the bootloader is then used for regular development.

Given the way this hardware combination works, it's not surprising you
have to fiddle a bit with the parameters before it might work.

If you want something more powerful and reliable, you have to use an
FTDI chip that implements the MPSSE (Multi-protocol synchronous serial
engine), like an FT2232D.  (Or, get one of the official Atmel tools,
or an USBasp, or a USBtiny programmer.)

Never trust an operating system you don't have sources for. ;-)
