They don't show up in /sys/kernel/debug/gpio, are not present in 
/sys/bus/i2c/devices/ but SPI core instead tries add them with a bogus 
Chip Select number:

[    5.727699][    T1] pxa2xx-spi pxa2xx-spi.5: cs56 >= max 4
[    5.733545][    T1] spi_master spi5: failed to add SPI device 
INT3491:00 from ACPI
