To make the story short, sony-laptop will replace sonypi and all the
(not so) active development is being done solely on sony-laptop.
Thus sony-laptop supports more models, the meye module also switched to
sony-laptop.

sony-laptop uses sysfs while sonypi creates a char device. To make
old users of the char device still work there is this
CONFIG_SONYPI_COMPAT option that makes sony-laptop also create the char
dev and accept the ioctls that sonypi accepts.
Enabling CONFIG_SONYPI_COMPAT would make the dismissal of sonypi easier
and the transition smoother.
Last but not least, since sony-laptop is ACPI based, it is automatically
loaded in recent kernels where a SNY5001 or a SNY6001 device is found in
the DSDT, and it will grab the ioports that also sonypi uses thus
making the 2 not cohexist happily. If CONFIG_SONYPI_COMPAT is set the
user won't notice the difference.
