I have patched the usbasp support for use of 3 MHz SCK as in the UsbAsp-flash firmware:
https://github.com/nofeletru/UsbAsp-flash
(I am not the author of this firmware, however I have tested it and find it useful).

My patch tests the capabilities of the firmware using the USBASP_FUNC_GETCAPABILITIES request, so there should be no influence on the devices which do not support 3 MHz. I have looked into the firmware's code, and it would be theoretically possible to increase the SCK speed up to 6 MHz, but this would be only reasonable when the target's F_CPU would be >18 MHz, which I think is rare.
