kernel parameter for disabling write-cache as like "hdparm -W0 /dev/sda"

is it possible to disable write cache using a kernel parameter ? I have a problem with my macbook pro 7.1 with a solid state disk.

installing fedora from a live cd is only possible with write cache disabled "hdparm -W 0 /dev/sda". if i leave write cache enabled the installation fails with error messages like :

kernel: ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen

because write-cache is enabled by default booting after the installation fails with error messages like above.
