Here is a VME to iSA adapter intended for MEga STE/TT - http://freenet-homepage.de/68k/pdf/nova_adapter.pdf
Found working link of that: ftp://ftp.pigwa.net/stuff/mirror/ataritt030.info/upload/schematy/nova_adapter.pdf Fascinating!
I used to also have an ET4000 - my first 'fast' graphics card for DOS. Would run up to a 16 mhz ISA Bus (20 mhz with artifacting)...
THat's pretty hardcore :-) Mine was on a 386-25DX Gateway 2000 with a Micronics motherboard, 4MB of RAM. Never tried to change bus speeds or anything, it was an expensive machine didn't want to break it. I do remember having switches hooked to the sound cards to adjust the IRQs though.
