Yup, it's a pain!
I have done something similar to what Paul mentions above, however on my car on the passenger side I can get spanners/sockets onto the nuts via a single extra hole that I cut just in front of the rear suspension joint. Use of extension bars takes it to the front suspension joint nut.
On the drivers side I can access all nuts and bolt without extra holes cut into anything.
But it is a bit tight and requires some fiddling with socket extensions and UJ's! In addition when assembling for the first time, with tons of access, bear in mind which way you want the bolts put through the hole to allow easier removal in the future.
