Then the "2232HIO" programmer should work fine. Connect it like so:
FTDI           ATtiny4/5/9/10
SCK------------TPICLK
TDI/DO--R--+
           +---TPIDATA
TDO/DI--R--+
TMS------------RESET
(Have a look at AVR918, p. 8 for a better diagram, but use R = 1kΩ or something 
like that.)
Remember to use 5V, otherwise writing to flash fails. (For me, reading the 
signature bytes worked with 3.3V).
If you have the RSTDISBL fuse programmed, then you have to apply 12V to the 
RESET pin of the ATtiny (haven't tried that yet).

Best regards,
Hannes
