If replacing U58 doesn't cure the mobo, try with the resistors again and check the voltages - I'm curious if the bit 4 will still show different readings. In fact if you get odd voltages still, remove U58 from socket and measure again. There's a '373 connected there that could have a faulty input.
I did a quick test and motherboard won't boot - same behaviour, although it did a nice clear long beep one time instead of this screeching noise.
So what exactly should I check again? With or without resistors in 8288?
With pin4 and pin7 8288 resistors and nothing else U58 voltages are like this (same with F245 and old S245):
#1 0,11
#2 4,74
#3 4,74
#4 4,74
#5 4,74
#6 4,74
#7 4,74

#9 4,74
#10 0,01
#11 1,80
#12 1,80
#13 1,79
#14 1,79
#15 2,2
#16 1,80
#17 1,80
#18 1,80
#19 0,22
#20 4,74
with U58 removed from it's socket:
