Mostly installed the new machine. It took a while, because I didn't have a floppy for ages, I always install machines via hard disk copy, including lilo-ing them in the old machine. Most of the time this worked out ok, but now it didn't. First, the kernel failed to boot (reset after decompression). I tried to get rid of K7 optimizations, no go. Finally it occured to me that the APIC shouldn't be enabled with a K6. Then, at the early boot sequence, the new machine still crapped out with what looked like a corrupted filesystem, and lo, putting it back to the working one, indeed, it got corrupted. It took another while still I discovered that during boot, it set the IDE to UDMA/66 on a VIA controller which is capable only to UDMA/33... Majorly "restructuring" the boot filesystem in the progress.
But it's ok, by 01:35 (AM for you USians) I was ready, just forgot the BIOS/ATA settings in the most conservative state, and going to sleep early. Now, what day would be better for our remote sites to have urgent problems at 06:00 than this same day?
