The Pluto-P board uses the serial configuration method, with DCLK hooked to the parport nStrobe pin and DATA hooked to the parport Data0 pin.
This simple program uploads a .rbf programming file to a Pluto-P board attached to the first parallel port. It runs in about .6 seconds on my system. Since each bit takes 3 'outb's to program, the "microsecond rule" implies that the minimum time is around 480ms.
P.S. I've tried but failed to get the Altera software to run under wine. Xilinx does have no-cost software for Linux. If I ever make my own FPGA design, that would be a pretty important factor in deciding.
Update: The HAL driver for this board has been included in emc since version 2.2
