Hm, I don't seem to have the scripts anymore. But python re is fairly simple.
Here's a hacky script to parse a table, perform some transformations on it and
print out the C defines:

#!/usr/bin/env python

import re
import sys

d = file(sys.argv[1]).readlines()


for line in d:
	r = re.compile(r"\|\| `0x([0-9A-Fa-f]+)` \|\| ([\w\s\(\)/]+) \|\|")
	m = r.match(line)
	if m:
		offset = int(m.group(1), 16)
		name = m.group(2)
		name = name.replace("workAround", "workaround")

		origname = name

		name = name.replace("(", " ")
		name = name.replace(")", " ")

		name = name.upper()
		name = name.strip()

		name = name.replace(" ", "_")
		name = name.replace("/", "_")
		name = name.replace("CONTROL", "CTL")
		name = name.replace("COMMON", "COMM")
		name = name.replace("CALIBRATION", "CALIB")
		name = name.replace("DEBUG", "DBG")
		name = name.replace("COUNTER", "CNT")
		name = name.replace("POWER", "PWR")
		name = name.replace("B_PHY", "B")
		name = name.replace("ADDRESS", "ADDR")
		name = name.replace("OUT_ENABLE", "OUTEN")
		name = name.replace("THRESHOLD", "THRES")
		name = name.replace("STATUS", "STAT")
		name = name.replace("COEFFICIENT", "COEFF")
		name = name.replace("INTERVAL", "INT")
		name = name.replace("TIMEOUT", "TO")
		name = name.replace("VALUE", "VAL")
		name = name.replace("SAMPLE", "SMPL")

		name = "B43_LPPHY_" + name

		nr_tabs = 5 - (len(name) / 8)
		tabs = "\t" * nr_tabs

		comment = origname

		if (offset & 0x400):
			accessor = "B43_PHY_OFDM"
		else:
			accessor = "B43_PHY_CCK"
		offset &= ~0x400;
		if (offset & ~0xFF):
			print "offset ERROR %X" % offset
			sys.exit(1)
		sys.stdout.write("#define %s%s%s(0x%02X)" % (name, tabs, accessor, offset))
		if comment:
			sys.stdout.write(" /* %s */" % comment)
		sys.stdout.write("\n")
	else:
		pass
		print "NO match " + line
