Is there ever going to be a method for hotswapping kernels between SHA and Scrypt? Kinda want to get a dualminer, but don't want to completely shut off the more-lucrative SHA mining completely to mine Doge
I'm not sure what you mean by "hotswapping kernels". Kernels are for GPU mining, not ASIC mining.
BFGMiner already supports Dual Mode mining with DualMiner ASICs, just not with the 5-chip GridSeed Orbs. I doubt that will ever be supported, as there is very little demand. Most controller software has already disabled or deprecated mining SHA with the Scrypt ASICs and newer Scrypt ASICs don't support the feature at all.
