Ok, I've added support, it is enabled through macros defined at the top of dslash_quda.cu.:
DIRECT_ACCESS_WILSON_SPINOR - the neighbouring spinor loads
DIRECT_ACCESS_WILSON_ACCUM - the x load in Xpay kernels
DIRECT_ACCESS_LINK - the gauge field
Defining these macros enables direct reading (through L1 on Fermi), otherwise the texture cache is used.
Unfortunately, this only seems to decrease performance on my 480, so I've left the default as textured reads throughout.
