STM32F429I SDRAM controller without byte select

I waited for a 208 pin version for about a year and it is still not available (RUTRONIC now has 14 weeks wait time). So I want to try the STM32F429I (176 pins) for driving an RGB888 LCD with 32-bit SDRAM. It is "kinda" possible if I sacrifice byte select in the FMC controller. According to the manual I can live without it because a) read mode does not use it and b) for writing I can always align my data to a 4-byte boundary. The question is, will the SDRAM controller work with byte select disabled/uninitialized?
