Mmmmm, I took a look at lcrash and I'll refrain from commenting on it's method of operation here to avoid too much public swearing. Yuck! Anyway, it seems that lcrash at least only accesses the memory using read() and write()? which means it is relatively easy to using a struct page flag to do uncached vs cached access on the fly. mmap on the other hand would be a bit of a nightmare as it would require a custom fault handler that would know when to go cached and when not to. How would you feel about using PG_arch_1 for this on ia64?
