Alternative SPI pins - Raspberry Pi Forums
this question joan seems know answers , fortunate does! wish had half talent!
seems me information have able find broadcom gpio pins 7,8,9,10 & 11 become ce1, ce0, miso,mosi & sclk when spidev enabled.
question this, using joan's pigpio, possible use different pins ce,miso,mosi , clk such broadcom's gpio 28,29,30 & 31 found on p5 socket if 1 solder 8pin idc header there?
and, if so, possible use pigpio on header separately either spidev or kernel driver using 'normal' spi pins?

nope, because spi interface isn't available on pins http://elinux.org/rpi_bcm2835_gpios
try bit-banging spi on regular gpio pins, it'd slow.
dunno if software support there yet, in theory it's possible access second spi interface (spi1) on model b+ on gpios 16-21
(and on computemodule there potentially 3 separate spi interfaces available)
