128 byte reads are much more common than 32 byte reads. The message passing + setup/teardown for a read is much more expensive, in terms of time, than the reading itself. A slightly bigger struct is well worth the time savings. This reduces read times for /dev/eeprom from 57 seconds per 4KB to 14 seconds. Additionally, make sending the page address in the eeprom driver and utility optional. This can save a little time when reading within the same page and allows support for smaller devices that don't support pages (example: chips containing EDID).
